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.

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
The 'master' branch is where the development of the latest major version lives on. The development of all other major versions takes place in each branch whose name is identical to its major version number. For example, the development of 3.x and 4.x resides in the branch '3' and the branch '4' respectively.
