The following ruleset uses a map file to associate each Referer with a redirection target.

-RewriteMap deflector txt:/path/to/deflector.map
-
-RewriteCond %{HTTP_REFERER} !=""
-RewriteCond ${deflector:%{HTTP_REFERER}} =-
-RewriteRule ^ %{HTTP_REFERER} [R,L]

+
+RewriteCond %{HTTP_REFERER} !=""

RewriteRule ^.* ${deflector:%{HTTP_REFERER}} [R,L]
- The map file lists redirection targets for each referer, or, if we just wish to redirect back to where they came from, a "-" is placed in the map:
