[flexcoders] CF cgi.remote_user and Flex woes

[David Harris]

We have developed a Flex app that access the cgi.remote_user.
What we are finding is that when the Flex app accesses this CFC via a
remote object, it is inconsistent in return a value.

The results happen like this:
The user browses to the MXML file for the first time.
Clicks the "Check CGI user", and returns OK, then clicks it again, and
[empty string] is displayed,
and clicks again and the correct result is displayed.
Then the user refreshes the browser, and only [empty string] is
returned every time.

IIS has anonymous access turned off, and it is on the local intranet for them.
I have been told it is running on Windows2003.

Has anyone else come across this before?
If so, how did you fix it?

Cheers,

David
