Log In Returns Blank Page

[RSalameh]

I am running ColdFusion MX 6.1 with JRun 4 Updater 6. I have a web application
that requires authentication. After entering in my credentials,
ColdFusion/JRun returns a blank page. I have to refresh the page before being
taken into the site. This happens about 50% of the time and it just recently
started happening after applying JRun4 Updater 6. The ColdFusion MX logs do
not report any information on this. Any ideas what may be causing this to
happen? Help would be much appreciated.

Thanks,
Ramzi:confused;

Use LiveHTTPHeaders extension for Mozilla to see what is sent from the
server. Also check page source when the page is blank, maybe there are some
clues there...

View source shows nothing on the page. I also downloaded a utility to record the http traffic between the client browser and server. What should I be looking for?

Location: headers and general communication... Also you could enable
debugging to see what files are processed.

After enabling debugging, I noticed that the last page processed on the blank
login page is the "application.cfm" file. When the login is successful there
are a few other pages that are processed after the "application.cfm" file.
As far as http traffic goes, when the login is successful, I noticed that
there are an extra six http requests. After these first six requests, the
communication between client and server is identical.
Also for your information, I rolled back the installation on our production
servers to the last JRun 4 Updater and I no longer have these problems. That
implies that our coding is fine. There is another thread that I'm following on
Google Groups. You may find it at

Anyhow, if you have any additional information on this, I would really
appreciate it. Thanks for all of your help insofar.
