Name
    rewrite_request_body

Description
    This is a nginx module that reads HTTP POST and PUT request body in the rewrite phase
    for nothing in order for you to use $request_body to rewrite urls in nginx's config.

Installation
    Get the nginx source code (tested with nginx-1.2.3) from nginx.net ( http://nginx.net/ ).
    Unpack the source code and build nginx with this module.

    $ wget 'http://sysoev.ru/nginx/nginx-X.X.X.tar.gz'
    $ tar -xzvf nginx-X.X.X.tar.gz
    $ cd nginx-X.X.X/

    $ git clone https://github.com/tszming/nginx-rewrite-request-body-module.git
    $ ./configure --add-module=nginx-rewrite-request-body-module
    $ make -j2
    $ make install

Usage
    rewrite_request_body;

    example:

        # nginx.conf

        upstream pool1  {
            server 127.0.0.1:8081;
            server 127.0.0.1:8082;
        }
        
        upstream pool2 {
            server 127.0.0.1:8083;
        }

        location / {
        
            rewrite_request_body;
            
            proxy_pass http://pool1;
            
            if ($request_body ~* 'test') {
                proxy_pass http://pool2;
            }
        }
