The http_reply_access rules are similar to http_access, except that they are checked after Squid receives the HTTP response headers for a cache miss. You might want to use this access list to deny requests based on some characteristic of the response, such as the content type.

Syntax	http_reply_access allow|deny [!]ACLname ...
