Dear Monks

Apologies for the OT nature of this node (but it is affecting a Perl app!)

I am in the process of deploying a Perl web app that makes use of cookies to store user credentials and data. I fully expected that the app could be deployed and running in minutes but I have hit a problem which appears to be caused by the cookie headers not reaching the web server. This is not a situation that I have encountered before and I would be most grateful for your collective wisdom.

The application can be accessed by IP address, DNS name or by a local name set up in the hosts file. The cookies are only being lost when the DNS name is used. To my mind, this points to a network device (firewall, load balancer etc.) that is intercepting the calls to the server and stripping out the headers. Has any other monk encountered a similar issue? The operations people who installed the server don't know whether there is a firewall and haven't been able to talk to the network guys...

Here are the details of the setup:

• The application is being deployed on a Windows 2000 server on our internal network.
• Web server is IIS
• Activstate Perl 5.6.1 is installed and running (and checks out in terms of running the rest of the app that doesn't require cookies)

Many thanks in advance for helpful suggestions!
