What does IE's Automatic caching setting do?
Posted on 2004-09-13
According to Microsoft, setting IE to Automatic caching does the following:
"This is the same as the previous setting [Every time you start Internet Explorer], but with a logic algorithm to understand the habits of Web page behavior. This setting specifies that when you return to a page you viewed previously, Internet Explorer should not check to see whether the page has changed since you last viewed it.
If you select this setting, Internet Explorer checks for new content only when you return to a page that you viewed in an earlier session of Internet Explorer or on an earlier day. Over time, if Internet Explorer determines that images on the page are changing infrequently, it checks for newer images even less frequently. "
However, my experience is that, on the contrary, a page will be re-loaded within a single IE session, but I cannot figure out the rule behind it. Sometimes it does... sometimes it doesn't. Does anyone know how this really works?
