To get this going safely with Squid+Apache you will also need to do all of the following in addition to what you have already done: 1) Trail the list with an explicit "http_access deny all" to be sure the set controls only do what you want. 2) add an access control to allow apache requests through 3) setup a second ACL mirroring the 'proxyed' listing, which limits apache requests only to the requests that are actually allowed. 4) setup a *third* set of access controls on apache. To mirror the accepted content in 'proxyed' file and block apache from being an open-proxy in it's own place. Amos
