IE Bug

[Guest]

Hi,
I am using IE Explorer v6 with Windows XP (HE) SP2 ...
When I am on Amazon (I dont recall it appearing on any other site ..) and if
I have to use the 'Back' button on my browser I continually get a 'Page
cannot be displayed message'. When I refresh I get the following message:

Attention: There appears to be a bug in the web browser you are currently
using. Here are some ways to get around the problem:
To return to the page you were previously on: --click the BACK button on
your browser's navigation bar until you reach the desired page.
To checkout --click on the shopping cart icon at the top of the page and
proceed through the checkout process using the standard server (instead of
the secure server). You can phone or fax the credit card information to us.
Your Web browser is Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1;
..NET CLR 1.1.4322).

Its driving me crazy! Is there a workaround? Is the problem with my browser
or something on the Amazon site?

Thx,

Don-

Yes, this is a real bug in IE, the XP SP2 version. I've just been working on
this, because it's affecting the web application that I work on.

This happens under the following conditions:

- A browser submits an HTTP POST request
- The response contains the "cache-control=no-cache" directive
- The user navigates to another page, and then the user uses the back button
to return to the first page

If the user refreshes, as suggested, the page is retreived either by a
simple GET, or, if IE is actually sending a POST (as it should), it isn't
sending the POST parameters that were originally used to generate the page.

This tends to break web applications and transactional sites. It's going to
be an increasingly big problem for me, and (hopefully) an increasingly big
problem for Microsoft.

Christopher,

Problems with POST have had hotfixes available for quite a while.
It's possible that you need to get the latest IE rollup version and see
if the hotfixes that it includes fix your symptom.

E.g. here is one which suggests your version of urlmon.dll
will be significant:

<title>KB319792 - Back Navigation on POST Causes Re-POST in Internet Explorer 6</title>

and here is a possible version of that which would only be installed
if you had a hotfixed version:

<title>MS05-014: Cumulative Security Update for Internet Explorer (867282)</title>

<extract>
Urlmon.dll 6.0.2900.2598 27-Jan-2005 17:08 607,744 SP2QFE
</extract>

Etc.
