Hi Amos I have done some digging into your suggestion, and it looks like a better way to go for what I need to do. > Also, are you aware that current Squid versions can generate redirects > (custom headers included) based on output from an external_acl_type helper? > A helper to lookup your permissions system plus a few extra squid.conf > settings would be a lot simpler in terms of traffic processing and > bandwidth consumption than sending everything through an external ICAP > service. Are you able to point me in the direction of some sample config fragments that show how this can be done please. I am guessing that I would need to return some custom keyword / value pairs from the external_acl and set other acls based on the values. What I am aiming at is to selectively bump or redirect (or both) based on the client status and the site being requested. Thanks again. Darren B.

What I am doing is just setting the Expires value in the RESP_MOD response when I return a 307 redirect so I can control how long the caches (both Squid and the browser) hang on to it. > > > > In that case you should be using Cache-Control:max-age=NN instead where > the NN being your desired TTL in seconds.
