[SOLVED] Redirection on Apache (Maintain POST params)

Issue

I have Apache installed on my server and I need to redirect from http to https. The reason for this is our load balancer solution cannot hand https so requests come in on http and then we transfer them to https using the below lines in the httpd.conf file.

<VirtualHost 10.1.2.91:80>
     Redirect 302 /GladQE/link https://glad-test.com/GladQE/link.do
</VirtualHost>

This works fine for GET requests but POST requests will lose the parameters passed on the URL. What would be the easiest way to perform this redirect and maintain POST params?

I need to get from http://glad-test.com/GladQE/link.do to here https://glad-test.com/GladQE/link.do maintaining POST params

Thanks

Tom

Solution

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/.
