If you just want to change one or two cached files once and do not care that they will be replaced by fresher copies eventually (possibly immediately; see P.S.), then you can very carefully hand-edit the cached content on disk and restart Squid (to get rid of in-memory cached copies, if any). You have to preserve the old content length of the edited response and all [binary] metadata. Most editors will not do that for you. A response may even contain a Content-MD5 checksum. This hack is technically possible in some cases but it is unsupported. Otherwise, what you want to do is called Content Adaptation. There are several ways to do it as summarized at http://wiki.squid-cache.org/SquidFaq/ContentAdaptation HTH, Alex. P.S. Squid may get a fresh copy from the origin server if you tell the browser to refresh the page or if Squid decides to refresh it for other reasons. Your refresh patterns may combat some of these problems. Please note that the patterns you used did not reach this mailing list. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
