Dwayne:

This is not going to work. The only time that anything will be
visible is during the initial establishment of the SSL connection
between the client (browser) and the server. After the SSL
connection is established, the HTTP request from the client and the
HTTP response from the server are encrypted. You won't be able to
apply your filtering rules.

I am not part of the Squid development team and haven't used the
HTTPS features. This feature only makes sense when Squid is being
used as a front-end to a server where the SSL connection is being
established between the client and the Squid proxy server with
communications between the Squid proxy server and the HTTP server
being performed without encryption.

I'm sure that the Squid development team will correct me if I am wrong.
