On a CSS, if a manual expiration time (say two hours) is set for an arrowpoint-cookie, does the expiration time get reset with every subsequent transaction through the switch? Or is the expiration time set once, at the initial HTTP GET request, and the cookie vanishes at it's expiration time?
If the cookie expiration time isn't constantly updated, then it's possible that a user might lose his cookie after two hours (even though he's only been idle for a minute or two) and lose his server persistence.
One says that when the cookie expires it is still sent to the CSS by the browser which will then replace it with a new cookie, so the user will remain stuck to the same server.
Another says that once the cookie expires it is removed from the browser, so that the CSS would see the incoming traffic as an entirely new session, and make a new balancing decision and assign a new cookie. This makes more sense to me as it is how I believe browsers handle cookies.
If you set a cookie expiration time, and DON'T set arrowpoint-cookie browser-expire, then the CSS will note the expired cookie and reset a new one. Not sure what this gets you over a non-expiring cookie, except maybe it will allow for recycling of IDs if you've got gazillions of sticky customers.
If you set cookie expiration time AND set arrowpoint-cookie browser-expire, then the cookie vanishes from the browser upon it's expiration time, and the CSS has to make a brand-new decision.
