How to limit mod_rewrite to a single directory?

Can you help with my htaccess mod_rewrite clean URL formula?

• I run a directory with about 100 pages, and im using an htaccess file so that users can type for example... mysite.com/courier opposed to; mysite.com/COURIER.php?subtype=COURIER heres how I am going about it; RewriteRule ^courier\.*$ COURIER\.php?subtype=COURIER [NC,L,N] RewriteRule ^valeting\.*$ VALETING\.php?subtype=VALETING [NC,L,N] RewriteRule ^sales\.*$ SALES\.php?subtype=SALES [NC,L,N] instead of writing a new RewriteRule for every single page, is there a RewriteRule I can use that would cover each of my pages?

• Answer:

  Off the top of my head, something like : RewriteRule ^(.*)$ $1php?subtype=$1 [NC,L,N] so whatever is matched in the (.*) is replaced into the $1 (1 as its the first match, $2 ,$3 etc. if there are multiple matches) Be careful though and try it out a few times. Why duplicate code (valeting.php, courier.php, sales.php) as well as passing the type? One php file with the passed type would be easier to maintain. you should put some validation into the code.php to check the subtype is ok. If I were you I'd do something like : RewriteRule ^(.*)$ code.php?subtype=$1 [NC,L,N]
