MySQL + htaccess mod_rewrite?

Med RewriteMap allt är möjligt:

RewriteMap examplemap prg:/path/to/file.php
RewriteRule (.*) ${examplemap:$1}

Du kan använda mod_dbd likaså:

DBDriver mysql
DBDParams "host=localhost,user=db_user,pass=password,dbname=db"
RewriteMap myquery "dbd:select new_url from rewrite where old_url = %s" 
RewriteRule (.*) ${myquery:$1}
