Redirection on Apache (Maintain POST params)

Standard Apache redirects will not be able to handle POST data as they work on the URL level. POST data is passed in the body of the request, which gets dropped if you do a standard redirect.

You have an option of either using a PHP script to transparently forward the POST request, or using a combination of Rewrite (mod_rewrite) and Proxy (mod_proxy) modules for Apache like follows:

RewriteEngine On
RewriteRule /proxy/(.*)$ http://www.example.com/$1 [P,L]

P flag passes the request to the Proxy module, so anything that comes to your site (via GET or POST doesn't matter) with a URL path starting with a /proxy/ will transparently be handled as a proxy redirect to http://www.example.com/.

For the reference:

• http://httpd.apache.org/docs/current/mod/mod_proxy.html

You can try with the HTTP status code 307, a RFC compilant browser should repeat the post request. Reference: http://en.wikipedia.org/wiki/List_of_HTTP_status_codes

In contrast to how 302 was historically implemented, the request method is not allowed to be changed when reissuing the original request. For instance, a POST request should be repeated using another POST request.

To change from 302 to 307, do that:

<VirtualHost 10.1.2.91:80>
     Redirect 307 /GladQE/link https://glad-test.com/GladQE/link.do
</VirtualHost>
