Just a simple [] guy, hacking Perl for fun and profit since way back in the last millenium. You may find me hanging around in the monestary [].

What am I working on right now? Probably the Sprog project [].

User-Agent Atrocities

[ #20773 ]

During a recent Apache log analysis, I found the record for excessively long User-Agent strings went to this 208 character monster:

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; {94FD9F9D-4102-4372-897E-CE34BF1ED774}; ESB{8B286AD5-9080-43E2-9467-745492862693}; Hotbar; ODI3 Navigator; MSN 6.1; MSNbMSFT; MSNmen-nz; MSNc00; v5m)

I hadn't previously encountered browser plugins (spyware?) that add a GUID to you User-Agent - presumably to allow your activities to be tracked across domains and even if you have cookies disabled. This poor sucker has two!

Apparently the .NET runtime installer appends its version information to the IE User-Agent too. This person must be some sort of beta junkie:

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; .NET CLR 1.0.2914; .NET CLR 2.0.40607)

What's the longest/weirdest User-Agent you've found in your Apache log?
