thanks for the info. I can see how it would work for redirecting any page to another page in say another directory.
perhaps i should explain what i'm trying to accomplish. I have a php script that will allow me to edit any page on my site, while looking at the page in the browser. it's very usefull as all changes are done in realtime and on the actual page, so you can really speed the editing side of things up a lot.
The only problem with this functionality is, every single request for a page will include these php options, through an include. So for heavy traffic sites, it can add a lot of processing overhead. Especially since these functions are rarely used, only when editing a page.
So my solution for this is to create another php script that will re assemble any desired page to add the php scripts needed for the editor functionality.
I could go through an admin panel and then navigate to the desired page and that would work fine, but i want to streamline the whole process by allowing me to add a suffix to any standard url. such as my "admin.sys" and then have htaccess redirect the requested url to a specific php file. which will further process the request in the desired manner.
The only thing about this issue is that the original requested URL needs to be processed by the final php file redirected to by htaccess.
So there we go, any ideas.
