Hi gang,

This seems like it should be trivial, but I cannot find reference material for it.

I need to get the GUID assigned to a user when he/she accesses a web page. I was under the impression (not sure why) that IIS generated one for each session. Is that true?

I am looking for the defined 32-character id (block of 8, three blocks of 4, block of 12).

I know I could make one, but I need to make sure it is GLOBALLY unique, hence the use of the Guid.

Thanks for any input, even if it is an alternate solution.

Cheers,

Chris

Hi there,

IIS doesn't hand out IDs; it's ASP or ASP.NET that does that. However, unique as the ASP.NET Session ID may look, I don't think it's guaranteed to be unique.

Creating a Guid is simple. In .NET you can do this:

Guid myGuid = Guid.NewGuid(); // C#

Dim myGuid As Guid = Guid.NewGuid() ' VB

In SQL Server, you can use SELECT NewId()

In all cases, you get a globally unique ID.

Cheers,

Imar

Thanks, Imar. I just found an article about that.

My misconceptions lead me astray more often than I would like...
