ASP.NET SessionID type

Question

I was wondering if anyone knew what was the format of a ASP.NET SessionID? It's not a GUID or base64, what is its type? Also does it vary from version to version of the .NET framework?

thanks

Edited. Revised from my original dumb answer.

The documentation just says it's randomly asigned by ASP.NET. http://msdn.microsoft.com/en-us/library/system.web.sessionstate.httpsessionstate.sessionid.aspx

Another page gives a bit more detail.

The ASP.NET session identifier is a randomly generated number encoded into a 24-character string consisting of lowercase characters from a to z and numbers from 0 to 5.
