Making template system

[Red Blaze]

Hello,

I'm trying to find ways to control my website with just one template.php file, and the only way I can think of at the moment is with htaccess.

Options +FollowSymlinks
RewriteEngine on

RewriteRule ^$ /controller.php [L]

I want every url to point to controller.php since depending on the URL, controller.php will select the correct filename from an XML file.

for instance, xmldemo.astralaxiom.net would point to controller.php; selecting the main homepage by default.
xmldemo.astralaxiom.net/Contact-Us would point to controller.php as well, but in the script I have prepared, searches for the "Contact-Us" in the XML.

I just want htaccess to point to controller.php, doesn't matter what URL they type in. I made a huge google search for 2-3 weeks, but can't find my solution. Everything I come up with gives me an Internal Error, because it keeps looping.

Options +FollowSymlinks
RewriteEngine on

RewriteRule ^$ /controller.php [L]
RewriteRule ^([^/]*)$ /controller.php [L]

I tried this, but I believe it keeps looping, causing the Internal Error.

Any help would be greatly appreciated.
