Motivation: HttpProxyHandler uses `NetUtil#toSocketAddressString` to compute CONNECT url and Host header. The url is correct when the address is unresolved, as `NetUtil#toSocketAddressString` will then use `getHoststring`/`getHostname`. If the address is already resolved, the url will be based on the IP instead of the hostname. There’s an additional minor issue with the Host header: default port 443 should be omitted. Modifications: * Introduce NetUtil#getHostname * Introduce HttpUtil#formatHostnameForHttp to format an InetSocketAddress to HTTP format * Change url computation to favor hostname instead of IP * Introduce HttpProxyHandler ignoreDefaultPortsInConnectHostHeader parameter to ignore 80 and 443 ports in Host header Result: HttpProxyHandler performs properly when connecting to a resolved address

How to build
For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.
You require the following to build Netty:
- Latest stable Oracle JDK 7
- Latest stable Apache Maven
- If you are on Linux, you need additional development packages installed on your system, because you'll build the native transport.
Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.
Branches to look
Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>
. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
Usage with JDK 9
Netty can be used in modular JDK9 applications as a collection of automatic modules. The module names follow the reverse-DNS style, and are derived from subproject names rather than root packages due to historical reasons. They are listed below:
io.netty.all
io.netty.buffer
io.netty.codec
io.netty.codec.dns
io.netty.codec.haproxy
io.netty.codec.http
io.netty.codec.http2
io.netty.codec.memcache
io.netty.codec.mqtt
io.netty.codec.redis
io.netty.codec.smtp
io.netty.codec.socks
io.netty.codec.stomp
io.netty.codec.xml
io.netty.common
io.netty.handler
io.netty.handler.proxy
io.netty.resolver
io.netty.resolver.dns
io.netty.transport
io.netty.transport.epoll

(native

io.netty.transport.sctp
io.netty.transport.udt
Automatic modules do not provide any means to declare dependencies, so you need to list each used module separately
in your module-info
file.
