Mod_rewrite rule if no other rules match

Is there a way 开发者_C百科to do a sort of "catch all" rule that will only be matched if no other rules have been matched in my .htaccess file?

---

Put this rule as last rule to catch any request that could not be mapped onto an existing file:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ catch-all.foo

if you put your rule at the bottom, and have your other rules with a [L], it'll be considered the catch-all.
