Thanks for your advice, Jon and Alan -- after more than a week of waiting, I still haven't been admitted to the plone-users list by the moderators. Kudos to this group for at least having an open subscription policy.
I've also since solved the problem through my own research, and so forgive me for posting this solution to this forum, but I want this to be out there for posterity and Google searches. This isn't the Apache cookie bug, because I'm not using Apache, I'm using a product called ISAPI_Rewrite from Helicon Tech that emulates mod_rewrite for IIS. This problem is a known bug with versions 3.1.0.67 and earlier of that product that has since been fixed by the vendor, so a simple update is enough to fix it. Here is a link to the relevant thread from the vendor's support forum: http://www.helicontech.com/forum/13634-Weird_cookie_problem.html -- Greg Delisle Cornell Lab of Ornithology http://www.birds.cornell.edu On Sat, Nov 13, 2010 at 11:18 AM, Alan Runyan <[email protected]> wrote: > Move to plone-users mailing list.
