Browser support for "sessions" to make them longerSubmitted by brad on Mon, 2011-10-03 11:27
I'm actually not a fan of login and sessions on the web, and in fact prefer a more stateless concept I call authenticated actions to the more common systems of login and "identity."
But I'm not going to win the day soon on that, and I face many web sites that think I should have a login session, and that session should in fact terminate if I don't click on the browser often enough. This frequently has really annoying results -- you can be working on a complex form or other activity, then switch off briefly to other web sites or email to come back and find that "your session has expired" and you have to start from scratch.
There are times when there is an underlying reason for this. For example, when booking things like tickets, the site needs to "hold" your pending reservation until you complete it, but if you're not going to complete it, they need to return that ticket or seat to the pool for somebody else to buy. But many times sessions expire without that reason. Commonly the idea is that for security, they don't want to leave you logged on in a way that might allow somebody to come to your computer after you leave it and take over your session to do bad stuff. That is a worthwhile concept, particularly for people who will do sessions at public terminals, but it's frustrating when it happens on the computer in your house when you're alone.
Many sites also overdo it. While airlines need to cancel your pending seat requests after a while, there is no reason for them to forget everything and make you start from scratch. That's just bad web design. Other sites are happy to let you stay "logged on" for a year.
To help, it would be nice if the browser had a way of communicating things it knows about your session with the computer to trusted web sites. The browser knows if you have just switched to other windows, or even to other applications where you are using your mouse and keyboard. Fancier tools have even gone so far as to use your webcam and microphone to figure if you are still at your desk or have left the computer. And you know whether your computer is in a public space, semi-public space or entirely private space. If a browser, or browser plug-in, has a standardized way to let a site query session status, or be informed of session changes and per-machine policy, sites could be smarter about logging you out. That doesn't mean your bank still should not be paranoid if you are logged in to a session where you can spend your money, but they can be more informed about it.
