Oh right, we do allow 443 as well. And our IT department just installed a proxy here too.
WHAT A PAIN! I've been filing case after case getting them to re-open access to sites I need.
And, there's some bizarre feature that I don't completely understand, where all HTTPS traffic
is forwarded through the proxy and so it comes with the wrong (or anyway additional)
encryption, so signatures don't match and all sorts of other messy things. Of course the
thing is only tightly integrated with Internet Explorer, so if you use any other browser, even
on Windows, you have to enter your password info, which then times out again (how anyone can
imagine that promoting the use of IE is a security _enhancement_ utterly escapes me but...)
I've arrived at work in the morning and had 100's of dialogs I have to get rid of from my RSS
feeds, my weather applets, etc. when my password times out after I've left for the day.
It's hard for me to believe the benefits really outweigh the costs here, but I guess I only
see the costs and not the benefits.
