There are many questions with similar titles, but I couldn't find any asking the same thing.
Most sites that support user login have a "remember me" functionality, where you can check a box and have your session persist through multiple browsing sessions.
Are there any standards or best practices or recommendations in terms of how long the session should last until it expires again? What about for how the expiration time is "refreshed" (e.g. if it expires in one month, should it be updated to one month away on every logged-in page view, or handled some other way)?
