Can someone tell me what does that in IE when logging?

Hi,

The followwing is IE but what is the "{XXXXXX}" in between?
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; {C81XXC47-80AC-7324-593A-A0AFAX18B07}; .NET CLR 1.1.4322; InfoPath.1; .NET CLR 2.0.50727)
I really wonder what it means?

The characters between the {} are a GUID. GUIDs are unique strings that people can generate -- they were invented by Microsoft (I think) and are used to identify applications, database objects, and other things where a unique identifier is required.

Why that browser has a GUID, I can't tell you, but that's what the string is.
