i appreciate that (it is prepended to the md5-hex part of the cookie).
and it is a convenient way to index sessions DB in HT.
however beyond that, i see no purpose for it.
and in the case of making sessions persistent without saving any 
state on the HT system, they seem irrelevant and need to be 
side-stepped.
hence why i am trying to index the session DB using the md5-hex part 
of the cookie only.
