htaccess RewriteRule The page isn't redirecting properly

Question

This is my first time trying to write htaccess rules. My target is to make all relative links to be redirected to absolute. To begin i was testing:

RewriteEngine On

RewriteRule gallery\.php$ http://www.domain.com/sample/gallery.php
RewriteRule info\.php$ http://www.domain.com/sample/gallery.php

The first rule makes Firefox throw the error "The page isn't redirecting properly" when I click on the link, while the second rule works fine. The idea for the future was to write a rule like,

RewriteRule catchAllRelativeLinks$ http: //www.domain.com/sample/$1

but if I can't make the first rule work I don't think I will find how to make the real rule.

EDIT: to avoid the endless loop can't i try to understand if i am on the first or second istance by catching a variable ? some ideas i tried (and faild):

RewriteCond %{IS_SUBREQ} false
RewriteRule ^gallery\.php$ http://www.domain.com/gallery.php?a [R=302,L]

RewriteCond %{THE_REQUEST} !(\?something)$
RewriteRule ^gallery\.php$ http://www.domain.com/gallery.php?something [R=302,L]

or with an environment variable,

thanks again

Answer 1

The first rule you have results in an endless loop. mod_rewrite isn't all that great at making relative links absolute. That should be done in the HTML. For example, turning

<a href="gallery.php">Gallery</a>

into

<a href="/sample/gallery.php">Gallery</a>

However, the second rule works because it does something mod_rewrite does extremely well, and that's redirecting from one page or URL to another. For more information on this please see, the Apache documentation .

You can checkout this link for detailed explanation.

This worked for me (:

RewriteEngine on

    # Check for POST Submission | 
    # Because POST parameters aren't retained on a redirect.
    # You can omit that line if you want to make sure that all POST submissions are secure   
    # (any unsecured POST submissions will be ignored)
    RewriteCond %{REQUEST_METHOD} !^POST$

    # Forcing HTTPS
    RewriteCond %{HTTPS} !=on [OR]
    RewriteCond %{SERVER_PORT} 80
    # Pages to Apply
    RewriteCond %{REQUEST_URI} ^something_secure [OR]
    RewriteCond %{REQUEST_URI} ^something_else_secure
    RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]
