Are You All Beard Lovers?

Hi-

acct: csense/colonial
domain: colonialsense.com

This is probably for un4given....

Got a super-weird problem: our site is a custom CMS...basically, every url that comes in is redirected (passing url) to CSPage.php, which parses the url & builds each page appropriately. Anything not parsable to a valid url is 404'd.

So, consider the following urls:

http://colonialsense.com/How-To_Guides/C...d_Rugs.php
http://colonialsense.com/How-To_Guides/C...conces.php

Each loads as expected. But if you try to go to:

http://colonialsense.com/How-To_Guides/C...Horses.php

you get a 403 Forbidden error saying "You don't have permission to access /CSPage.php on this server."

Interestingly enough, if you cut the url to:

http://colonialsense.com/How-To_Guides/C...Shavin.php

you get the standard 404 page, as you do with 'Shavinx.php', 'Shavina.php', and others...but when you try:

 http://colonialsense.com/How-To_Guides/C...having.php

the 403 error pops back up.

I've checked error logs & permissions and haven't a clue. This CMS has been running for over 6 years and I've never had an instance where a single url generates a permissions issue...basically, the .htAccess just says to rewrite the url to CSPage.php and the CMS takes over from there....but it's not even getting to CSPage.php and I can't think of a single reason why...

...unless you guys are such beard afficienados that you've blocked the word 'shaving' from all urls! :-)

...any clues appreciated...

Many thnx,
