Using outdated Cached Page

I don't notice stale pages on most of the sites
I visit, but there is one site in particular that
I always see the cached page--even if I haven't
visited in a very long time. I don't understand
why I have problems with only one site.

I have changed my IE Settings of "Check for newer
versions of stored pages" from "Automatically" to
"Every time you start Internet Explorer". I still
get the stale version of the site.

Their HTML source begins:
<HTML>
<HEAD>
<!-- #BeginEditable "metas" -->
<META NAME="language" CONTENT="eng">
<META NAME="resource-type" CONTENT="document">
<META NAME="robots" CONTENT="All">
<META NAME="rating" CONTENT="General">
<META HTTP-EQUIV="Content-Type" CONTENT="text/html;
charset=iso-8859-1">
<META HTTP-EQUIV="Expires" CONTENT="20020101"><!-- #EndEditable -->

Is there anything they can add to their HTML to make
my browser reload the page? Does IE's caching look
for a last-modified META entry?

Thanks,
Tony

Does Cntrl-F5 force a clean page load? If so, then it is a web page
problem. If not, then perhaps the proxy server is caching. As I
remember one can set lifetime for pages on a proxy server by setting
some HTTP headers. Hope someone else knows the details.

As far as the WWW is concerned, the key issue is what the HTTP headers
say. See http://www.mnot.net/cache_docs/ if you want to understand this.

rubbish, but irrelevant here
<META HTTP-EQUIV="Expires" CONTENT="20020101">
Rubbish. It might as well say CONTENT="garbage" for that matter.

No, there isn't. This is meant to be an HTTP function. How else would
you expect it to work for GIFs, JPEGs, PDFs and all that lot?
Cacheability isn't exclusive to HTML by any means.

Well, IE tends to add an extra layer of problems, since it often does what
misguided authors expect, in preference to what the WWW specifications
require.

However, if you go to that tutorial, you'll find a reference to the
author's cacheability engine. If you point one of those engines at the
URL in quetion, it will deliver a report, which might just help to
understand what's going on.

If something of interest turns up, please do report it back to the group.

The changes Tony Barker has made in his IE configuration should make his
browser send the same http headers (particularly : Cache-Control) to the
server as if you were pressing manually Ctrl+F5

When I go to the web page I see an old stale page. If I then press
Cntrl-F5, the page reloads and I see the current page.

My IE "Check for newer versions of stored pages" setting is
still set to "Every time you start Internet Explorer".

When you say "it is a web page problem", what are they doing
wrong?

Thanks,
Tony
