Hi, I have a link sharing site set up for a few months now and I have noticed the way the URL's are rewritten aren't exactly search engine friendly, here is a example http://theultimatelinksharingsite.c...zuki/96 - Suzuki DR 650 Service Repair Manual I would like to replace the %20 with a underscore so it would read: http://theultimatelinksharingsite.c...zuki/96_-_Suzuki_DR_650_Service_Repair_Manual As I understand it the URL's are rewritten in htaccess, here is the bulk of the code: Options +FollowSymlinks RewriteEngine on RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_URI} ^/([0-9]+?)$ RewriteRule ^(.+?)$ index.php?page=$1 RewriteCond %{REQUEST_FILENAME} !-f t RewriteCond %{REQUEST_URI} ^/(.+?)/(.+?)/(([0-9]|[^0-9]).+?)$ RewriteRule ^(.+?)/(.+?)/(.+?)$ viewlink.php?category=$1&sub_category=$2&link=$3 [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_URI} ^/(.+?)/(.+?)/([0-9]+?)$ RewriteRule ^(.+?)/(.+?)/(.+?)$ index.php?category=$1&sub_category=$2&page=$3 [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_URI} ^/([^/]+)/([^/]+)$ RewriteRule ^(.+?)/(.+?)$ index.php?category=$1&sub_category=$2 [L] I would be very greatful if someone could point me in the right direction. Thanks, Brian
that is up to your script to provide links and canonical tag in <head> with the proper url, not mod_rewrite. mod_rewrite will pass it along, YOUR script has to understand Suzuki_DR_650_Service_Repair_Manual. this is an issue in your PHP, not an issue in htaccess
