IE constantly caching

Hi, I have a funny problem with one of our websites (www.uskf.org). In IE it
always seems to be a cached version. I have set IE to always check for newer
versions of pages.

In Firefox a new version of the page is always loaded, and using a command
line browser, lynx, I get the most recent version. If I download using a
script based on the WinHTTPRequest object, I get an old cached version.

Is there a problem with how IE is interpreting the page headers?

The headers on the page are the following:
<META NAME="RESOURCE-TYPE" CONTENT="DOCUMENT">
<META NAME="DISTRIBUTION" CONTENT="GLOBAL">
<META NAME="ROBOTS" CONTENT="INDEX, FOLLOW">
<META NAME="REVISIT-AFTER" CONTENT="1 DAYS">
<META NAME="RATING" CONTENT="GENERAL">
<META HTTP-EQUIV="PAGE-ENTER" CONTENT="RevealTrans(Duration=0,Transition=1)">
<style id="StylePlaceholder"></style>
<LINK id="_DesktopModules_SimpleGallery_Random" rel="stylesheet"
type="text/css" href="/DesktopModules/SimpleGallery
Random/module.css"></LINK><LINK
id="_DesktopModules_DnnForge___LatestArticles" rel="stylesheet"
type="text/css" href="/DesktopModules/DnnForge -
LatestArticles/module.css"></LINK><LINK id="_DesktopModules_ICPC_Counter"
rel="stylesheet" type="text/css"
href="/DesktopModules/ICPC-Counter/module.css"></LINK><LINK
id="_Portals__default_" rel="stylesheet" type="text/css"
href="/Portals/_default/default.css"></LINK><LINK
id="_Portals_667_Skins_DNNToolSet_Portfolio_" rel="stylesheet"
type="text/css"
href="/Portals/667/Skins/DNNToolSet.Portfolio/skin.css"></LINK><LINK
id="_Portals_667_" rel="stylesheet" type="text/css"
href="/Portals/667/portal.css"></LINK>
<script src="/js/dnncore.js"></script>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">

Any advice would be greatly appreciated

I think the HTTP 1.1 response headers can override the HTML Meta directives.

Try using FiddlerTool to discover the exact symptom details.

Also, once a component is cached if your cache checking setting
is Every visit... what matters is the what the server does with the
browser's requests. E.g. if the browser is saying (in effect):
"I have this. Can I use it?" and the server gives the go ahead
it seems to me that the error is on the server not in the browser.
FiddlerTool would help you decide if that was happening
and also allow you to compare what exactly your other browsers
are doing differently.

BTW if a caching server is the problem you may be able to
circumvent it without clearing your cache simply by pressing
Ctrl-F5.


Good luck
