Keep RTSPRequestEncoder, RTSPRequestDecoder, RTSPResponseEncoder and
RTSPResponseDecoder for backwards compatibility but they now just extends
the generic encoder/decoder and are markes as deprecated.
Renamed the decoder test, because the decoder is now generic. Added
testcase for when ANNOUNCE request is received from server.
Created testcases for encoder.
Mark abstract base classes RTSPObjectEncoder and RTSPObjectDecoder as
deprecated, that functionality is now in RTSPEncoder and RTSPDecoder.
Added annotation in RtspHeaders to suppress warnings about deprecation, no need when
whole class is deprecated.
Motivation:
We should prevent to add/set DefaultHttpHeaders to itself to prevent unexpected side-effects.
Modifications:
Throw IllegalArgumentException if user tries to pass the same instance to set/add.
Result:
No surprising side-effects.
Motivation:
As we stored the WebSocketServerHandshaker in the ChannelHandlerContext it was always null and so no close frame was send if WebSocketServerProtocolHandler was used.
Modifications:
Store WebSocketServerHAndshaker in the Channel attributes and so make it visibile between different handlers.
Result:
Correctly send close frame.
Motivaion:
The HttpHeaders and DefaultHttpHeaders have methods deprecated due to being removed in future releases, but no replacement method to use in the current release. The deprecation policy should not be so aggressive as to not provide any non-deprecated method to use.
Modifications:
- Remove deprecated annotations and javadocs from methods which are the best we can do in terms of matching the master's api for 4.1
Result:
There should be non-deprecated methods available for HttpHeaders in 4.1.
Motivation:
There currently exists http.HttpUtil, http2.HttpUtil, and http.HttpHeaderUtil. Having 2 HttpUtil methods can be confusing and the utilty methods in the http package could be consolidated.
Modifications:
- Rename http2.HttpUtil to http2.HttpConversionUtil
- Move http.HttpHeaderUtil methods into http.HttpUtil
Result:
Consolidated utilities whose names don't overlap.
Fixes https://github.com/netty/netty/issues/4120
Motivation:
Whe a 100 Continue response was written an IllegalStateException was produced as soon as the user wrote the following response. This regression was introduced by 41b0080fcc.
Modifications:
- Special handle 100 Continue responses
- Added unit tests
Result:
Fixed regression.
Motivation:
The HttpObjectAggregator always responds with a 100-continue response. It should check the Content-Length header to see if the content length is OK, and if not responds with a 417.
Modifications:
- HttpObjectAggregator checks the Content-Length header in the case of a 100-continue.
Result:
HttpObjectAggregator responds with 417 if content is known to be too big.
Motivation:
When attempting to retrieve a SPDY header using an AsciiString key, if the header was inserted using a String based key, the lookup would fail. Similarly, the lookup would fail if the header was inserted with an AsciiString key, and retrieved using a String key. This has been fixed with the header simplification commit (1a43923aa8).
Extra unit tests have been added to protect against this issue occurring in the future. The tests check that a header added using String or AsciiString can be retrieved using AsciiString or String respectively.
Modifications:
Added more unit tests
Result:
Protect against issue #4053 happening again.
Motivation:
A degradation in performance has been observed from the 4.0 branch as documented in https://github.com/netty/netty/issues/3962.
Modifications:
- Simplify Headers class hierarchy.
- Restore the DefaultHeaders to be based upon DefaultHttpHeaders from 4.0.
- Make various other modifications that are causing hot spots.
Result:
Performance is now on par with 4.0.
Motivation:
Due not using a cast we insert 32 and not a whitespace into the String.
Modifications:
Correclty cast to char.
Result:
Correct handling of whitespaces.
Motivation:
In the event an HTTP message does not include either a content-length or a transfer-encoding header [RFC 7230](https://tools.ietf.org/html/rfc7230#section-3.3.3) states the behavior must be treated differently for requests and responses. If the channel is half closed then the HttpObjectDecoder is not invoking decodeLast and thus not checking if messages should be sent up the pipeline.
Modifications:
- Add comments to clarify regular decode default case.
- Handle the ChannelInputShutdownEvent in the HttpObjectDecoder and evaluate if messages need to be generated.
Result:
Messages are generated on half closed, and comments clarify existing logic.
Motivation:
We noticed that the headers implementation in Netty for HTTP/2 uses quite a lot of memory
and that also at least the performance of randomly accessing a header is quite poor. The main
concern however was memory usage, as profiling has shown that a DefaultHttp2Headers
not only use a lot of memory it also wastes a lot due to the underlying hashmaps having
to be resized potentially several times as new headers are being inserted.
This is tracked as issue #3600.
Modifications:
We redesigned the DefaultHeaders to simply take a Map object in its constructor and
reimplemented the class using only the Map primitives. That way the implementation
is very concise and hopefully easy to understand and it allows each concrete headers
implementation to provide its own map or to even use a different headers implementation
for processing requests and writing responses i.e. incoming headers need to provide
fast random access while outgoing headers need fast insertion and fast iteration. The
new implementation can support this with hardly any code changes. It also comes
with the advantage that if the Netty project decides to add a third party collections library
as a dependency, one can simply plug in one of those very fast and memory efficient map
implementations and get faster and smaller headers for free.
For now, we are using the JDK's TreeMap for HTTP and HTTP/2 default headers.
Result:
- Significantly fewer lines of code in the implementation. While the total commit is still
roughly 400 lines less, the actual implementation is a lot less. I just added some more
tests and microbenchmarks.
- Overall performance is up. The current implementation should be significantly faster
for insertion and retrieval. However, it is slower when it comes to iteration. There is simply
no way a TreeMap can have the same iteration performance as a linked list (as used in the
current headers implementation). That's totally fine though, because when looking at the
benchmark results @ejona86 pointed out that the performance of the headers is completely
dominated by insertion, that is insertion is so significantly faster in the new implementation
that it does make up for several times the iteration speed. You can't iterate what you haven't
inserted. I am demonstrating that in this spreadsheet [1]. (Actually, iteration performance is
only down for HTTP, it's significantly improved for HTTP/2).
- Memory is down. The implementation with TreeMap uses on avg ~30% less memory. It also does not
produce any garbage while being resized. In load tests for GRPC we have seen a memory reduction
of up to 1.2KB per RPC. I summarized the memory improvements in this spreadsheet [1]. The data
was generated by [2] using JOL.
- While it was my original intend to only improve the memory usage for HTTP/2, it should be similarly
improved for HTTP, SPDY and STOMP as they all share a common implementation.

Motivation:
WebSocketServerHandshakerFactory.sendUnsupportedVersionResponse does not
send a LastHttpContent, nor does it flush, and it doesn't send a content
length.
Modifications:
Changed sendUnsupportedVersionResponse to send FullHttpResponse, to
writeAndFlush, and to set a content length of 0. Also added a test for
this method.
Result:
Upstream handlers will be able to determine the end of the response, the
response will actually get written to the client, and the client will be
able to determine the end of the response.
Proposal to fix issue #3636
Motivations:
Currently, while adding the next buffers to the decoder
(`decoder.offer()`), there is no way to access to the current HTTP
object being decoded since it can only be available currently once fully
decoded by `decoder.hasNext()`.
Some could want to know the progression on the overall transfer but also
per HTTP object.
While overall progression could be done using (if available) the global
Content-Length of the request and taking into account each HttpContent
size, the per HttpData object progression is unknown.
Modifications:
1) For HTTP object, `AbstractHttpData` has 2 protected properties named
`definedSize` and `size`, respectively the supposely final size and the
current (decoded until now) size.
This provides a new method `definedSize()` to get the current value for
`definedSize`. The `size` attribute is reachable by the `length()`
method.
Note however there are 2 different ways that currently managed the
`definedSize`:
a) `Attribute`: it is reset each time the value is less than actual
(when a buffer is added, the value is increased) since the final length
is not known (no Content-Length)
b) `FileUpload`: it is set at startup from the lengh provided
So these differences could lead in wrong perception;
a) `Attribute`: definedSize = size always
b) `FileUpload`: definedSize >= size always
Therefore the comment tries to explain clearly the different behaviors.
2) In the InterfaceHttpPostRequestDecoder (and the derived classes), I
add a new method: `decoder.currentPartialHttpData()` which will return a
`InterfaceHttpData` (if any) as the current `Attribute` or `FileUpload`
(the 2 generic types), which will allow then the programmer to check
according to the real type (instance of) the 2 methods `definedSize()`
and `length()`.
This method check if currentFileUpload or currentAttribute are null and
returns the one (only one could be not null) that is not null.
Note that if this method returns null, it might mean 2 situations:
a) the last `HttpData` (whatever attribute or file upload) is already
finished and therefore accessible through `next()`
b) there is not yet any `HttpData` in decoding (body not yet parsed for
instance)
Result:
The developper has more access and therefore control on the current
upload.
The coding from developper side could looks like in the example in
HttpUloadServerHandler.
Motivation:
We need to ensure we never allow to have null values set on headers, otherwise we will see a NPE during encoding them.
Modifications:
Add unit test that shows we correctly handle null values.
Result:
Verify correct implementation.
Motivation:
Found a bug in that netty would generate a 20 byte body when returing a response
to an HTTP HEAD. the 20 bytes seems to be related to the compression footer.
RFC2616, section 9.4 states that responses to an HTTP HEAD MUST not return a message
body in the response.
Netty's own client implementation expected an empty response. The extra bytes lead to a
2nd response with an error decoder result:
java.lang.IllegalArgumentException: invalid version format: 14
Modifications:
Track the HTTP request method. When processing the response we determine if the response
is passthru unnchanged. This decision now takes into account the request method and passthru
responses related to HTTP HEAD requests.
Result:
Netty's http client works and better RFC conformance.
Motivation:
* Path attribute should be null, not empty String, if it's passed as "Path=".
* Only extract attribute value when the name is recognized.
* Only extract Expires attribute value String if MaxAge is undefined as it has precedence.
Modification:
Modify ClientCookieDecoder.
Add "testIgnoreEmptyPath" test in ClientCookieDecoderTest.
Result:
More idyomatic Path behavior (like Domain).
Minor performance improvement in some corner cases.
RFC6265 specifies which characters are allowed in a cookie name and value.
Netty is currently too lax, which can used for HttpOnly escaping.
Modification:
In ServerCookieDecoder: discard cookie key-value pairs that contain invalid characters.
In ClientCookieEncoder: throw an exception when trying to encode cookies with invalid characters.
Result:
The problem described in the motivation section is fixed.
Motivation:
The usage and code within AsciiString has exceeded the original design scope for this class. Its usage as a binary string is confusing and on the verge of violating interface assumptions in some spots.
Modifications:
- ByteString will be created as a base class to AsciiString. All of the generic byte handling processing will live in ByteString and all the special character encoding will live in AsciiString.
Results:
The AsciiString interface will be clarified. Users of AsciiString can now be clear of the limitations the class imposes while users of the ByteString class don't have to live with those limitations.
Related: #3445
Motivation:
HttpObjectDecoder.HeaderParser does not reset its counter (the size
field) when it failed to find the end of line. If a header is split
into multiple fragments, the counter is increased as many times as the
number of fragments, resulting an unexpected TooLongFrameException.
Modifications:
- Add test cases that reproduces the problem
- Reset the HeaderParser.size field when no EOL is found.
Result:
One less bug
Motivation:
Currently CORS can be configured to support a 'null' origin, which can
be set by a browser if a resources is loaded from the local file system.
When this is done 'Access-Control-Allow-Origin' will be set to "*" (any
origin). There is also a configuration option to allow credentials being
sent from the client (cookies, basic HTTP Authentication, client side
SSL). This is indicated by the response header
'Access-Control-Allow-Credentials' being set to true. When this is set
to true, the "*" origin is not valid as the value of
'Access-Control-Allow-Origin' and a browser will reject the request:
http://www.w3.org/TR/cors/#resource-requests
Modifications:
Updated CorsHandler's setAllowCredentials to check the origin and if it
is "*" then it will not add the 'Access-Control-Allow-Credentials'
header.
Result:
Is is possible to have a client send a 'null' origin, and at the same
time have configured the CORS to support that and to allow credentials
in that combination.
Motivation:
At the moment if you want to return a HTTP header containing multiple
values you have to set/add that header once with the values wanted. If
you used set/add with an array/iterable multiple HTTP header fields will
be returned in the response.
Note, that this is indeed a suggestion and additional work and tests
should be added. This is mainly to bring up a discussion.
Modifications:
Added a flag to specify that when multiple values exist for a single
HTTP header then add them as a comma separated string.
In addition added a method to StringUtil to help escape comma separated
value charsequences.
Result:
Allows for responses to be smaller.
In testEncodingSingleCookieV0():
Let's assume we encoded a cookie with MaxAge=50 when currentTimeMillis
is 10999.
Because the encoder will not encode the millisecond part for Expires,
the timeMillis value of the encoded Expires field will be 60000. (If we
did not dropped the millisecond part, it would be 60999.)
Encoding a cookie will take some time, so currentTimeMillis will
increase slightly, such as to 11001.
diff = (60000 - 11001) / 1000 = 48999 / 1000 = 48
maxAge - diff = 50 - 48 = 2
Due to losing millisecond part twice, we end up with the precision
problem illustrated above, and thus we should increase the tolerance
from 1 second to 2 seconds.
/cc @slandelle
Motivation:
Internet Explorer doesn't honor Set-Cookie header Max-Age attribute. It only honors the Expires one.
Modification:
Always generate an Expires attribute along the Max-Age one.
Result:
Internet Explorer compatible expiring cookies. Close#1466.
Motivation:
HttpContentDecoder had the following issues:
- For chunked content, the decoder set invalid "Content-Length" header
with length of the first decoded chunk.
- Decoding of FullHttpRequests put both the original conent and decoded
content into output. As result, using HttpObjectAggregator before the
decoder lead to errors.
- Requests with "Expect: 100-continue" header were not acknowleged:
the decoder didn't pass the header message down the handler's chain
until content is received. If client expected "100 Continue" response,
deadlock happened.
Modification:
- Invalid "Content-Length" header is removed; handlers down the chain can either
rely on LastHttpContent message or ask HttpObjectAggregator to add the header.
- FullHttpRequest is split into HttpRequest and HttpContent (decoded) parts.
- Header (HttpRequest) part of request is sent down the chain as soon as it's received.
Result:
The issues are fixed, unittest is added.
Motivation:
Rfc6265Client/ServerCookieEncoder is a better replacement of the old
Client/ServerCookieEncoder, and thus there's no point of keeping both.
Modifications:
- Remove the old Client/ServerCookieEncoder
- Remove the 'Rfc6265' prefix from the new cookie encoder/decoder
classes
- Deprecate CookieDecoder
Result:
We have much better cookie encoder/decoder implementation now.
Motivation:
Currently Netty supports a weird implementation of RFC 2965.
First, this RFC has been deprecated by RFC 6265 and nobody on the
internet use this format.
Then, there's a confusion between client side and server side encoding
and decoding.
Typically, clients should only send name=value pairs.
This PR introduces RFC 6265 support, but keeps on supporting RFC 2965 in
the sense that old unused fields are simply ignored, and Cookie fields
won't be populated. Deprecated fields are comment, commentUrl, version,
discard and ports.
It also provides a mechanism for safe server-client-server roundtrip, as
User-Agents are not supposed to interpret cookie values but return them
as-is (e.g. if Set-Cookie contained a quoted value, it should be sent
back in the Cookie header in quoted form too).
Also, there are performance gains to be obtained by not allocating the
attribute name Strings, as we only want to match them to find which POJO
field to populate.
Modifications:
- New RFC6265ClientCookieEncoder/Decoder and
RFC6265ServerCookieEncoder/Decoder pairs that live alongside old
CookieEncoder/Decoder pair to not break backward compatibility.
- New Cookie.rawValue field, used for lossless server-client-server
roundtrip.
Result:
RFC 6265 support.
Clean separation of client and server side.
Decoder performance gain:

This commit closes#3221 and #1406.
Motivation:
HttpPostMultipartRequestDecoder threw an ArrayIndexOutOfBoundsException
when trying to decode Content-Disposition header with filename
containing ';' or protected \\".
See issue #3326 and #3327.
Modifications:
Added splitMultipartHeaderValues method which cares about quotes, and
use it in splitMultipartHeader method, instead of StringUtils.split.
Result:
Filenames can contain semicolons and protected \\".
Motivations:
It seems that slicing a buffer and using this slice to write to CTX will
decrease the initial refCnt to 0, while the original buffer is not yet
fully used (not empty).
Modifications:
As suggested in the ticket and tested, when the currentBuffer is sliced
since it will still be used later on, the currentBuffer is retained.
Add a test case for this issue.
Result:
The currentBuffer still has its correct refCnt when reaching the last
write (not sliced) of 1 and therefore will be released correctly.
The exception does no more occur.
This fix should be applied to all branches >= 4.0.
Motivation:
without this check then given a URI with path /path the resulting URL will be /path?null=
Modifications:
check that getRawQuery doesn't return null and only append if not
Result:
urls of the form /path will not have a null?= appended
Motiviation:
The HttpContentEncoder does not account for a EmptyLastHttpContent being provided as input. This is useful in situations where the client is unable to determine if the current content chunk is the last content chunk (i.e. a proxy forwarding content when transfer encoding is chunked).
Modifications:
- HttpContentEncoder should not attempt to compress empty HttpContent objects
Result:
HttpContentEncoder supports a EmptyLastHttpContent to terminate the response.
Motivation:
The commit 50e06442c3 changed the type of
the constants in HttpHeaders.Names and HttpHeaders.Values, making 4.1
backward-incompatible with 4.0.
It also introduces newer utility classes such as HttpHeaderUtil, which
deprecates most static methods in HttpHeaders. To ease the migration
between 4.1 and 5.0, we should deprecate all static methods that are
non-existent in 5.0, and provide proper counterpart.
Modification:
- Revert the changes in HttpHeaders.Names and Values
- Deprecate all static methods in HttpHeaders in favor of:
- HttpHeaderUtil
- the member methods of HttpHeaders
- AsciiString
- Add integer and date access methods to HttpHeaders for easier future
migration to 5.0
- Add HttpHeaderNames and HttpHeaderValues which provide standard HTTP
constants in AsciiString
- Deprecate HttpHeaders.Names and Values
- Make HttpHeaderValues.WEBSOCKET lowercased because it's actually
lowercased in all WebSocket versions but the oldest one
- Add RtspHeaderNames and RtspHeaderValues which provide standard RTSP
constants in AsciiString
- Deprecate RtspHeaders.*
- Do not use AsciiString.equalsIgnoreCase(CharSeq, CharSeq) if one of
the parameters are AsciiString
- Avoid using AsciiString.toString() repetitively
- Change the parameter type of some methods from String to
CharSequence
Result:
Backward compatibility is recovered. New classes and methods will make
the migration to 5.0 easier, once (Http|Rtsp)Header(Names|Values) are
ported to master.
Motivation:
The header class hierarchy and algorithm was improved on the master branch for versions 5.x. These improvments should be backported to the 4.1 baseline.
Modifications:
- cherry-pick the following commits from the master branch: 2374e17, 36b4157, 222d258
Result:
Header improvements in master branch are available in 4.1 branch.
Motivation:
The requirement for the masking of frames and for checks of correct
masking in the websocket specifiation have a large impact on performance.
While it is mandatory for browsers to use masking there are other
applications (like IPC protocols) that want to user websocket framing and proxy-traversing
characteristics without the overhead of masking. The websocket standard
also mentions that the requirement for mask verification on server side
might be dropped in future.
Modifications:
Added an optional parameter allowMaskMismatch for the websocket decoder
that allows a server to also accept unmasked frames (and clients to accept
masked frames).
Allowed to set this option through the websocket handshaker
constructors as well as the websocket client and server handlers.
The public API for existing components doesn't change, it will be
forwarded to functions which implicetly set masking as required in the
specification.
For websocket clients an additional parameter is added that allows to
disable the masking of frames that are sent by the client.
Result:
This update gives netty users the ability to create and use completely
unmasked websocket connections in addition to the normal masked channels
that the standard describes.
Motivation:
The 4.1.0-Beta3 implementation of HttpObjectAggregator.handleOversizedMessage closes the
connection if the client sent oversized chunked data with no Expect:
100-continue header. This causes a broken pipe or "connection reset by
peer" error in some clients (tested on Firefox 31 OS X 10.9.5,
async-http-client 1.8.14).
This part of the HTTP 1.1 spec (below) seems to say that in this scenario the connection
should not be closed (unless the intention is to be very strict about
how data should be sent).
http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html
"If an origin server receives a request that does not include an
Expect request-header field with the "100-continue" expectation,
the request includes a request body, and the server responds
with a final status code before reading the entire request body
from the transport connection, then the server SHOULD NOT close
the transport connection until it has read the entire request,
or until the client closes the connection. Otherwise, the client
might not reliably receive the response message. However, this
requirement is not be construed as preventing a server from
defending itself against denial-of-service attacks, or from
badly broken client implementations."
Modifications:
Change HttpObjectAggregator.handleOversizedMessage to close the
connection only if keep-alive is off and Expect: 100-continue is
missing. Update test to reflect the change.
Result:
Broken pipe and connection reset errors on the client are avoided when
oversized data is sent.
Related: #2983
Motivation:
It is a well known idiom to write an empty buffer and add a listener to
its future to close a channel when the last byte has been written out:
ChannelFuture f = channel.writeAndFlush(Unpooled.EMPTY_BUFFER);
f.addListener(ChannelFutureListener.CLOSE);
When HttpObjectEncoder is in the pipeline, this still works, but it
silently raises an IllegalStateException, because HttpObjectEncoder does
not allow writing a ByteBuf when it is expecting an HttpMessage.
Modifications:
- Handle an empty ByteBuf specially in HttpObjectEncoder, so that
writing an empty buffer does not fail even if the pipeline contains an
HttpObjectEncoder
- Add a test
Result:
An exception is not triggered anymore by HttpObjectEncoder, when a user
attempts to write an empty buffer.
Motivation:
Currently, when the CorsHandler processes a preflight request, or
respondes with an 403 Forbidden using the short-curcuit option, the
HttpRequest is not released which leads to a buffer leak.
Modifications:
Releasing the HttpRequest when done processing a preflight request or
responding with an 403.
Result:
Using the CorsHandler will not cause buffer leaks.
Motivation:
I was not fully reassured that whether everything works correctly when a websocket client receives the websocket handshake HTTP response and a websocket frame in a single ByteBuf (which can happen when the server sends a response directly or shortly after the connect). In this case some parts of the ByteBuf must be processed by HTTP decoder and the remaining by the websocket decoder.
Modification:
Adding a test that verifies that in this scenaria the handshake and the message are correctly interpreted and delivered by Netty.
Result:
One more test for Netty.
The test succeeds - No problems
Motivation:
Websocket performance is to a large account determined through the masking
and unmasking of frames. The current behavior of this in Netty can be
improved.
Modifications:
Perform the XOR operation not bytewise but in int blocks as long as
possible. This reduces the number of necessary operations by 4. Also don't
read the writerIndex in each iteration.
Added a unit test for websocket decoding and encoding for verifiation.
Result:
A large performance gain (up to 50%) in websocket throughput.
Motivation:
Currently we do more memory copies then needed.
Modification:
- Directly use heap buffers to reduce memory copy
- Correctly release buffers to fix buffer leak
Result:
Less memory copies and no leaks
Motivation:
The _0XFF_0X00 buffer is not duplicated and empty after the first usage preventing the connection close to happen on subsequent close frames.
Modifications:
Correctly duplicate the buffer.
Result:
Multiple CloseWebSocketFrames are handled correctly.
Motivation:
If the requests contains uri parameters but not path the HttpRequestEncoder does produce an invalid uri while try to add the missing path.
Modifications:
Correctly handle the case of uri with paramaters but no path.
Result:
HttpRequestEncoder produce correct uri in all cases.
Motivation:
HttpObjectAggregator currently creates a new FullHttpResponse / FullHttpRequest for each message it needs to aggregate. While doing so it also creates 2 DefaultHttpHeader instances (one for the headers and one for the trailing headers). This is bad for two reasons:
- More objects are created then needed and also populate the headers is not for free
- Headers may get validated even if the validation was disabled in the decoder
Modification:
- Wrap the previous created HttpResponse / HttpRequest and so reuse the original HttpHeaders
- Reuse the previous created trailing HttpHeader.
- Fix a bug where the trailing HttpHeader was incorrectly mixed in the headers.
Result:
- Less GC
- Faster HttpObjectAggregator implementation
Motivation:
DecodeResult is dropped when aggregate HTTP messages.
Modification:
Make sure we not drop the DecodeResult while aggregate HTTP messages.
Result:
Correctly include the DecodeResult for later processing.
Motivation:
Due to integer overflow bug, writes of FileRegions to http server pipeline (eg like one from HttpStaticFileServer example) with length greater than Integer.MAX_VALUE are ignored in 1/2 of cases (ie no data gets sent to client)
Modification:
Correctly handle chunk sized > Integer.MAX_VALUE
Result:
Be able to use FileRegion > Integer.MAX_VALUE when using chunked encoding.
