said by camper:Yup, that's true for many sites. Even if you elect to stay logged in, you have to re-enter your password to enter a more security-sensitive area of the site. (and I regard that behavior as a feature).
However, with the problem under discussion, you cannot even hit the home page without re-entering the login credentials. I proffer that the home page is not a more security-sensitive area.
I am not seeing that symptom. In fact, I just did a test wherein:
1. I logged out of my cookie initiated login session at comcast.net and then ended the browser session.
2. I cranked up the browser again, went to www.comcast.net and logged in again.
3. I next went to www.comcast.com in another browser tab, and I found that (as expected) I was still logged in.
4. I shut down both browser tabs and ended that browser session.
5. I launched the browser again and went to both www.comcast.net and www.comcast.com and found that I was still logged in at both sites.
6. I repeated the steps 1-5 twice more and I did not have any problem with either www.comcast.net or www.comcast.com not honoring the login cookie, or with requiring a separate login for www.comcast.com after I had already logged into www.comcast.net. The only exception was the account management password reaffirmation process that I previously discussed. And FWIW, the browser I use is SeaMonkey 2.13.2 (yes I know it is "out of date", but it works...if it ain't broke, don't fix it).
