LDN - Luminis Developer Network

Once in a while one of us gets a redirect loop on our Luminis login page. There are maybe ten of us using it and it occurs once every few weeks. This time it happened for me after Firefox crashed and restarted. If I clear the cookies it will stop looping.

We use SSL. That may be a clue.

Here are the headers for the first page it goes to (edited for privacy):

It keeps redirecting to the above url about 10 times in less than a second. Then it goes once to:
http://dev.college.edu/cp/home/logout?src=srs

Then once to:
http://dev.college.edu/jsp/misc/timedout.jsp

Then once to:
http://dev.college.edu/

Then once to:
http://dev.college.edu/cp/home/check/pre

Then once to:
http://dev.college.edu/cp/home/loginf

Then the loop starts over from the beginning, where it goes to:
https://dev.college.edu/cp/home/displaylogin
and loops on that url 10 times again...

Has anyone else experienced this? Any ideas what will prevent it?

Thanks.
