Assuming non-UUID's: Theoretically, yes. The CFID is only 4 digits long, and the CFTOKEN is 8 digits long. As a combination, this works out to about 100 billion unique values. If you have more sessions than that, I'm sure you have bigger problems! However, I'm one of those mathematical geeks that will only use a value for uniqueness if you can guarantee *pure* uniqueness.
Of course, by themselves, CFID and CFTOKEN would have a higher probability of duplicate values, since you can only have 10,000 different CFID values and 100,000,000 different CFTOKEN's. ----- Original Message ----- From: "Dave Carabetta" <[EMAIL PROTECTED]> To: "CF-Talk" <[EMAIL PROTECTED]> Sent: Wednesday, January 16, 2002 11:45 AM Subject: Re: Global UUID and Client vars > Billy, > > Actually, unless I'm reading what you wrote the wrong way, everybody who > uses SESSION or CLIENT variables is counting on unique CFIDs (and CFTOKENS > for that matter).
