Proxy and Browser Cache Control
Frequently you want your pages to be cached, so frequently
requested pages can be retrieved quickly.
However, for content that changes daily or more often, you may want to prevent
the page from being cached, either at the server or in the viewer's Temporary Internet Files.
To prevent caching of html pages, enter the following in the < meta> section of
the page head:
<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">
For an ASP application, go to Properties and the Home Directory tab in IIS , click the
Configure button, go to Application mappings and clear the Cache ISAPI
Applications check box.
Then, at the top of the .asp pages you do not want cached, add:
<% Response.Expires=0 %>
To prevent caching of .asp pages at the Proxy server, enter
<% Response.cachecontrol="private" %>
To enable caching of .asp pages at the Proxy server, enter
<% Response.cachecontrol="public" %>
