Name
    xss-nginx-module - Native cross-site scripting support in nginx

Synopsis

   # accessing /foo?callback=process gives the response
   # body "process(...);" (without quotes) where "..."
   # is the original response body of the /foo location.
   server {
        location /foo {
            # your content handler goes here...

            xss_get on;
            xss_callback_arg 'callback';
            xss_input_types 'application/json'; # default

    }

Description
    This module adds cross-site AJAX support to nginx. Currently only
    cross-site GET is supported. But cross-site POST will be added
    in the future.

Installation
    Grab the nginx source code from nginx.net (<http://nginx.net/>), for
    example, the version 0.8.32 (see nginx compatibility), and then build
    the source with this module:

        $ wget 'http://sysoev.ru/nginx/nginx-0.8.32.tar.gz'
        $ tar -xzvf nginx-0.8.32.tar.gz
        $ cd nginx-0.8.32/

        # Here we assume you would install you nginx under /opt/nginx/.
        $ ./configure --prefix=/opt/nginx \
            --add-module=/path/to/xss-nginx-module

        $ make -j2
        $ make install

    Download the latest version of the release tarball of this module from
    xss-nginx-module file list
    (<http://github.com/agentzh/xss-nginx-module/downloads>).

Compatibility
    The following versions of Nginx should work with this module:

    *   0.8.x (last tested version is 0.8.32)

    *   0.7.x >= 0.7.30 (last tested version is 0.7.64)

    Earlier versions of Nginx like 0.6.x and 0.5.x will *not* work.

    If you find that any particular version of Nginx above 0.7.30 does not
    work with this module, please consider reporting a bug.

TODO
    *   add cross-site POST support.
