Hello Rafa-el

in the phpbb forum I use this .htaccess

RewriteEngine On 
RewriteRule ^forums.* index.php 
RewriteRule ^forum([0-9]*).* viewforum.php?f=$1&mark=topic 
RewriteRule ^viewforum([0-9]*)-([0-9]*)-([0-9]*).* viewforum.php?f=$1&topicdays=$2&start=$3 
RewriteRule ^forum([0-9]*).* viewforum.php?f=$1 
RewriteRule ^ptopic([0-9]*).* viewtopic.php?t=$1&view=previous 
RewriteRule ^ntopic([0-9]*).* viewtopic.php?t=$1&view=next 
RewriteRule ^ftopic([0-9]*)-([0-9]*)-([a-zA-Z]*)-([0-9]*).* viewtopic.php?t=$1&postdays=$2&postorder=$3&start=$4 
RewriteRule ^ftopic([0-9]*)-([0-9]*).* viewtopic.php?t=$1&start=$2 
RewriteRule ^ftopic([0-9]*).* viewtopic.php?t=$1 
RewriteRule ^ftopic([0-9]*).html viewtopic.php?t=$1&start=$2&postdays=$3&postorder=$4&highlight=$5 
RewriteRule ^sutra([0-9]*).* viewtopic.php?p=$1

the .htaccess of vbulletinsuite

RewriteEngine on

Where is {REQUEST_FILENAME}?
