Mod_rewrite and Mod_ORT
ORT (Ovh Redirect Technology) is a module developped by OVH which permits the hosting of numerous important sites with less RAM used by the systems.
Mod_ort modifies the URI of the page and you may encounter a problem if you wish to use mod_rewrite. The solution consists of redefining the root rewrite of mod_rewrite:
RewriteRule ^/grp([0-9]+).php$ group.php?id=$1 [L]
RewriteRule ^/art([0-9]+).php$ article.php?id=$1 [L]
RewriteRule ^/age([0-9]+).php$ agenda.php?id=$1 [L]
RewriteRule ^/member_([0-9]+).php$ member.php?id=$1 [L]
need to be changed to:
RewriteRule ^/grp([0-9]+).php$ /group.php?id=$1 [L]
RewriteRule ^/art([0-9]+).php$ /article.php?id=$1 [L]
RewriteRule ^/age([0-9]+).php$ /agenda.php?id=$1 [L]
RewriteRule ^/member_([0-9]+).php$ /member.php?id=$1 [L]
