Hi all, I've developed a new external_acl helper. Its purpose is to add an artificial delay to requests flowing through squid. It is orthogonal to delay pools, the delay is added BEFORE serving the request (which can then be throttled by delay pools or not). It uses the multi-slot helper API - it is actually meant to be an example on how to write a multi-slot helper.
It's available at lp:~kinkie/squid/delayer (http://bazaar.launchpad.net/~kinkie/squid/delayer/files) If you can find the time to check it out, I'll then prepare an announcement for squid-users and a wiki page for it. Thanks -- /kinkie
