I don't have time to decode the hex, but I would first see if mod_deflate is running on your server.  If to, turn it off and see if the odd headers go away.

Subject: [Cialug] Weird Bad Header Request's with Chrome

I'm using Chrome with Ubuntu Netbook 10.10, testing out some local webpages. I noticed this first when running my django site, but I also use bottle.py and both of them keep showing weird requests like the following:

localhost.localdomain - - [16/Feb/2011 19:54:08] "GET / HTTP/1.1" 404 660

I tried firefox, hitting the same url only gave this for output

localhost.localdomain - - [16/Feb/2011 19:57:28] "GET /hello HTTP/1.1" 200 12
localhost.localdomain - - [16/Feb/2011 19:57:30] "GET /favicon.ico HTTP/1.1" 404 682

has anybody else noticed this behavior with chrome??
