I recentley captured the following data and I was wonder if anyone the meaning of the data being sent back to the site.

User-Agent: TSA/4.0.3.7
Tsl2/4.0.3.7
OS/Windows_XP Service Pack 1 2600
IE/62800.1106
CD/474636922
UID/2090068869
AID/43
NU/1

TSA,OS, and IE are obvious, what about the others? Is UID the SID of the user logged onto that particular system? Lots of questions, anyone got any answers?
