So rather than change it, I'd prefer to just document the behavior, so mea culpa and you were 100% correct.</p> <p style="margin: 10px 0 0 0">I updated both timeout and cacheAllowance docs to better reflect what it actually does.</p> <p style="margin: 10px 0 0 0">Normally when timeout is set, this isn't noticeably weird, but you are correct that it is noticeable when it's zero. cacheAllowance doesn't get added to lifetime but replaces it, so you either have to set it high enough to match, or leave it at 0 also.</p> <p style="margin: 10px 0 0 0">If you set cacheAllowance, however, to a really high number, it will result in more sessions hanging around in memory, but any attempt to use a session that's past its lifetime still breaks, that's a separate check regardless of whether the record is still available. So it's effectively usable as an upper bound on lifetime but practically speaking, setting timeout to zero in most cases would be accompanied by setting cacheAllowance to zero.</p> </td>
