Action canceled IFrame IE 6

[Dumitru Ozunu]

Hello,

I have a strange problem, I've browsed the whole newsgropu but I found no
answer :-(
I have a web page that contains a submit button (asp .net) when submited,
it makes a redirect to a page containing a IFRAME. sometimes the IFRAME
loads the page that it references without problems, sometimes I get a nasty
error: "Action canceled. Page could not be loaded", but the page exists on
my server and I can see it in my browser when I enter manually the path.
I've tested with various IE versions, but the problem appears only with IE
6 and IE 6 SP1. It appears when I call the page for the first time, when I
do a refresh or call the page later, it works.
Could someone help me?
Thanx,
mitru

What are you submitted? Is it a POST?

If so, it could be the web server not honoring extra POST crlf (carriage
return line feed) bytes.

It is pretty clear now that Microsoft updated the IE browser to comply with
the CERN specification for the POST command. However, it is breaking older
servers not expecting the change.

This is from the web site describing how the Apache Web server solved the
problem.

http://httpd.apache.org/docs/misc/known_client_problems.html

Read the first item about Trailing CRLF on POSTs.

We had a similar issue with the Wildcat! Web Server where the server was not
expecting the extra bytes. It doesn't show up all the time and it depends
alot on how much data is being posted and/or the transmission speed (both
ways, up and down). We added the logic to read the extra bytes and
VIOLA - problem goes away!

Anyway, the web server you are connecting to may not be expecting it. And
if it is not using TCP Half Close methods to perform a graceful socket
termination, to get rid of any extra bytes, you will see the behavior tons
of user are reporting "Page Cannot Be Displayed" in the past 2-3 weeks.
This has been the hottest topic with many users.

Yes, I do a POST. We use IIS 5.0 as web server. How can I get rid off CrLf
bytes?

Talk to Microsoft.

They have to change the server software.

I put of the detail analysis out there in more than one messages over the
last 2 weeks. Hopefully, if there is an MVP or Microsoft employee reading
this stuff "who really cares" and would pass it up (or down) the chain.

Its happening to many all over the place.
