> O'Reilly's Definitive Guide to HTML and XHTML has no reference in the index for either > Expires or Cache-control, so why would any web page contain such information? A web page wouldn't, but the HTTP response containing the HTML object/page may. ----------------------------------------------------------- Surely the web page author (i.e. myself) is responsible for specifying expiry and cache control details? ------------------------------------------------------------- > It looks like Squid will fail to serve most web pages. Is this a correct interpretation? Squid follows the HTTP specifications on what may be cached, and quite closely matches what the cacheability check engine reports. You can tweak this in by the refresh_pattern setting. -------------------------------------------------------- This is what I did before and got myself into terrible trouble. Do you have any suggestions for what to change?
