Yep. Eventually the session times out, but in the meantime a wandering user could theoretically accumulate a lot of garbage in their session.
(And it just occurs to me that a malicious user could exploit it to fill up the memory with junk) If however one follows the recomendations to keep the size of stuff in the session small (ie: dont be caching several megs of stuff!) then it probably still wouldn't amount to enough to be a serious problem in most cases - except on those very high traffic sites (ie: amazon.com). As a matter of principle however I don't particularly like have obsolete objects lying round when they should be made eligible for the GC - though of course I dont let this principle stop me from using the session ;-> -----Original Message----- From: David Graham [mailto:[EMAIL PROTECTED]] Sent: Friday, September 27, 2002 23:18 To: [EMAIL PROTECTED] Subject: RE: Please help decide a religious discussion Then the session times out and the list goes away automatically.
