Finally, Browsers like IE or Netscape allow the end-user some control over the process; you can set the browser to:
Check for new versions of stored pages
1) Every visit (Very slow)
2) Every time the browser starts (A bit better)
3) Automatically (The browser uses internal rules - good compromise)
4) Never (A lot of outdated pages, unless HTML forces a refresh)
We discussed this refresh stuff here a couple of months ago. For some unexplained reason, the settings in IE do not always take effect. To ensure it's doing what you want you have to check the registry, see
http://support.microsoft.com/support.../Q201/5/35.ASP Then there's those pages which have a Response.Expires = 0 command and will reload anyway whether you like it or not.
