Note this is the login attempt, not the loading of the initial page. You'll see in the NOT WORKING section that the browser does NOT return a cookie to the server, which is where the problem may be. Again, I'm not sure why - I'm thinking perhaps the browser/javascript is rejecting the cookie as it's missing the "secure" attribute (because the back-end is talking plain HTTP). As mentioned above Firefox has no issue with this. I've fired up an iCAP server but need to brush up on my Python before I can test what happens if I add the "secure" attribute.
