What is the math behind the sessionid?

[Bill]

I'm wondering how unique the sessionid is in ASP. What is the math
behind it's creation, and what are the probobolities of it being
reproduced, i.e. 1/10000? or 1 in twenty million? Can someone give me
some guidance on this? I'm trying to create some unique numbers for
data assignement, and would like a way that does not replicate.

Thanks,

Bill

Where are you storing the data?

Also, for creating unique IDs, you can use functions to return a GUID.

The Session ID's aren't intended to be unique for ever. Only as long as a
session is active. If you want unique values, you have a few choices, GUIDs
(as Chris suggested) or my favorite, incrementing numbers.
