Hi I wud like to understand one thing about MOD rewrite. Now since after using advanced seo MOD, urls are rewritten, how wud I know what is the actual page in case I need to make some changes to a page. Like I have a page .../forum/memberxxxx.html that displays members profile and I want to make some changes to the actual php page that generates profiles, how do I know which page is it ?

.htaccess :

#PROFILES
RewriteRule ^member([0-9]+)\.html$ /profile.php?mode=viewprofile&u=$1 [QSA,L]

so this means every memberxxxx.html gets redirected to profile.php

Thanks gowap
So that means whenever I need to see the original page I need to refer to my htaccess file and see which rule it applies to. Got it.

Exactly, the .htaccess is only making sure a given type of mod rewritten URL hits the proper php script (the only one to be able to build the pages).

So the phpBB structure is left untouched, viewtopic.php builds topic pages, viewforum.php forum's and etc ...
