-#
-# session_key 16 digit string identifying the session
-# session_id integer id of the record in the "sessions" table of the database
-# UNTIL_CLOSE a constant passed as session length to indicate "until browser window closes"
+# All session data is cached in globals, so:
+# 1. don't set large amonuts of data
+# 2. session_get() is very fast (no db access)
