+Summary: timeout and expire fields in SessionSQLServerHandler
+Hi everyone,
+  It seems that SessionSQLServerHandler (namespace
+System.Web.SessionState) doesn't correctly set nor retrieve the "expires"
+and "timeout" data fields in the database. Amongst other things, this
+prevents sessions to ever expire (this has serious security implications,
+which is why I proposed "Major" as a priority for this bug).
+  More precisely, I am about to attach a patch for version 1.1.15 which
+should correct the following issues:
+- in method "UpdateContext": delete expired sessions even before
+  checking that a particular session exists
+- in method "SelectSession": retrieve the value of "timeout" which
+  has been previously stored in the database instead of returning a
+  hardcoded value (100)
+- in method "InsertSession": set current time + timeout as the value
+  for "expires" instead of always current time + one day
+- in method "UpdateSession": update the "timeout" field (in case the user
+  changed it programmatically) and update the "expires" field accordingly
+- in methods "InsertSession" and "UpdateSession" : use the keyword
+  "NOW()" instead of supplying a numerical value for dates; this makes
+  the database server the only one to actually manipulate dates, which
+  avoids any potential clock synchronisation problems between the web
+  server(s) and the database server
+Nb: I'm not too sure about which type the data field "timeout" should be.
+    In this patch I assumed it was "decimal".
+  Hope this helps.
+Boris Dores
