Yeah...i did not realize this was an "issue" or that it was even Tracked/Counted. But i do not own a website, or even ponder that kind of "stuff".

Anyway.....i also stay logged in, for days, or even weeks at a time. I only have to Log In again if i have run some kind of scan that deletes that status. It kind of makes me curious.....why log in every day, why not just stay logged in 24/7.?
Supposing APUG is pure HTML, when you load a page your browser transmits your credentials to the server so that you don't have to type in the credentials. Even if your session expired, when you reload the page the credentials are transmitted again and a new session begins.
If that wasn't the case, the server would have to keep a huge number of sessions open. The server "purges" each session after a set amount of minutes without requests. The credentials are often stored in a cookie which will expire sooner or later so from time to time you will have to re-enter the credentials again. The credentials can also be stored by a mechanism of your web-browser.
[When you log-in, in that form, if you find a tick "keep me logged in" that means the server will send you a cookie with the next answer, and your browser will re-send that cookie at the next request, thus avoiding the explicit log-in with the form.
Even if you don't tick the "keep me logged" flag in the login form, your browser will probably ask you if you want it to remember the credentials for that site. That is a browser-based mechanism, which does not rely on cookies. In both cases, if you asked the server, or the browser, to remember your credentials, you will not have to log-in again because the browser will either do it for you or send a cookie to that effect. Both mechanisms must not be used when you are on a "public" computer, especially if you log in to your bank account! (or you web-based mail server etc.)].
The logging-in happens "under the hood" and you as a user might not be aware of it.
The server has no way to know if you are reading a page, or the state of your browser.
When you request a page, the server serves it and it then ignores (if it is pure HTTP/HTML site) your circumstances. You might close your browser and turn off your computer and the server would not know it. It would purge the session after the timeout.
APUG is not a pure HTTP/HTML site though, because while I am typing I am informed that there is a new "alert". There must be another communication channel open parallel to the pure "web" mechanism.
