Sorry Amos. But where else do I post this ? I thought I can mail it to this mail id squid-users@xxxxxxxxxxxxxxx. But if there is some other place, please let me know. - Anita -----Original Message----- From: Amos Jeffries [mailto:squid3@xxxxxxxxxxxxx] Sent: 15 February 2012 18:17 To: squid-users@xxxxxxxxxxxxxxx Subject: Re: Prefetch patch test Before we start. Please do not hijack other topics discussions. It ruins the groups archive threading and threaded mailer tools many of us use to track the group mail. Thank you.

It works normally for other requests though. I assume you means the prefetch project patch from devel.squid-cache.org? That was last updated for one of the 3.0 PRE-releases (5 or 6 by the looks of it). It was not accepted into mainline for some reason unknown to me. Apart from ESI support, all body content filtering and adaptations have been pushed off to ICAP and eCAP processors. The whole devel.* site is now outdated, all projects there are in the deprecated bin. If you would like to revive one please get in touch with squid-dev about joining development and be prepared for a fair bit of hacking to get it ported to current 3.HEAD in BZR. There are other tools (such as "squid-prefetch") which can do prefetch for any version of Squid without patching which you may want to investigate first. Although be aware the in most instances pre-fetching at the proxy level has usually been found to be a large waste of bandwidth and cache resources, with little benefits (or none) to offset the costs. Modern browsers do a different kind of pre-fetch themseves which has a far more efficient algorithm for calculating what resources to fetch early. Squid and other proxies do not have access to enough of the users information to do it efficiently. Amos Please do not print this email unless it is absolutely necessary.
