Session timeout revisiting
First, the session timeout is in effect only when you choose NO for "Automatically login when you return to the site?" when you edit your options. If you choose yes, you shouldn't be logged out after some minutes of inactive.
If you choose No:
The session timeout was set to 15 minutes. That is, if you write your post / message for 16 minutes or longer, you are logged out.
Now I set the session timeout to 30 minutes. So you have 30 minutes to compose IF you choose no for this option.
To those of you who want to know details about the cookies:
If you choose Yes for the above option:
a cookie is sent to you and saved on your computer. Whenever you come back to this forum, the cookie tells the forum that you are a valid user and you are auto-login.
If you compose a post for 31 minutes or longer, the cookie on your computer will tell the forum you are still logged in.
The disadvantage of choosing Yes: if someone else uses your computer and comes to this forum, he will be auto-login as you (using your username). To avoid this, you have to click on the Logout link every time you leave your computer, or you can choose No for the above option.
If you choose No for the above option:
You have to login manually every time you come back to the forum.
If you compose a message for 31 minutes or longer, you are logged out. So when you submit your post, you will get the famous (or infamous) "you are not logged in" message.
If you are inactive for more than 30 minutes, you are logged out. If you close all your browsers, you are logged out even if you are active in the past 30 minutes.
I hope this explanation is good enough for you guys to get a better idea about the cookie handling. Let me know if you still have questions.
