This is off-topic for this list, but I thought I'd just mention for those that are troubleshooting HTTP issues, there are useful plugins for both IE and Firefox that show you both incoming and outgoing HTTP headers, including through https connections.
For IE, there is an IE Explorer Bar add-on called ieHTTPHeaders: http://www.blunck.info/iehttpheaders.html You'll probably need to reboot after installing it for it to show up. For Firefox, there is an extension called LiveHTTPHeaders: http://livehttpheaders.mozdev.org/ I think it might work with Mozilla as well, but I haven't tried it. As always with software, use at your own risk. They work great for me. I thought this was of some relevance to this list, as many people using mod_perl tend to do its powerful header management capabilities. Tony
