Problems with cached pages by IE?
HTML pages allow for a special HTTP-EQUIV form of the META tag that specifies particular HTTP
headers from within the HTML document. Here is a short example HTML page that uses both Pragma:
no-cache and Expires: -1:
<HTML><HEAD>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
</HEAD><BODY>
</BODY>
</HTML>
Pragma: no-cache prevents caching only when used over a secure connection. A Pragma: no-cache META
tag is treated identically to Expires: -1 if used in a non-secure page. The page will be cached but
marked as immediately expired.
