How to Redirect POST Data to a Different Address with ProxyPass in Apache?

Redirecting POST Data with ProxyPass

It is possible to redirect POST data to a different address through server configuration. Here's how to achieve this using ProxyPass in Apache's .htaccess file:

1. Configure .htaccess:

In the .htaccess file located in the website's root directory, add the following rule:

# Redirect mail posting to index.php
RewriteRule send-mail index.php?send-mail [NC,P]

• [NC] means the rule is case-insensitive.
• [P] preserves POST data and passes it to the requested script.

2. Enable ProxyPass:

Ensure that the ProxyPass module is enabled in your server configuration. This can be done by adding the following line to the Apache configuration file (typically httpd.conf):

LoadModule proxy_module modules/mod_proxy.so

3. Edit Form Action:

Change the form's action attribute to the fake address used in the redirect rule:

<form action="/send-mail" method="post">

4. Handle POST Data in index.php:

In your index.php script, use the parse_str() function to extract POST data from the QUERY_STRING variable:

parse_str($_SERVER['QUERY_STRING'], $_POST);

This will make the POST data available to your PHP script, even though the request is being redirected.
