Motivation: In order to determine if a header contains a value we currently rely upon getAll(..) and regular expressions. This operation is commonly used during the encode and decode stage to determine the transfer encoding (e.g. HttpUtil#isTransferEncodingChunked). This operation requires an intermediate collection and possibly regular expressions for the CombinedHttpHeaders use case which can be expensive. Modifications: - Add a valuesIterator to HttpHeaders and specializations of this method for DefaultHttpHeaders, ReadOnlyHttpHeaders, and CombinedHttpHeaders. Result: Less intermediate collections and allocation overhead when determining if HttpHeaders contains a name/value pair.

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.
