We recently transitioned to a new version of our website, and in doing so, we seem to have created a problem for some of users in that they can't login. We can't seem to reproduce the problem on our own computers/browsers and we've tried several, but there are enough reports that we are sure something is going on. When we have worked closely with some of our users, we find that the aspxauth and the other cookies necessary for form authentication are not being created on their system. Most of these users are using Internet Explorer, but some on Chrome, and some say firefox as well. A lot of them solve the problem by switching to firefox.. but we'd like our site to continue to work for all browsers and we don't know what we are doing wrong. Our old site worked fine for all browsers.
I was wondering if anyone can tell me generally why internet explorer could be blocking these cookies on the new site, but not the old one, ...
