I noticed that now and again, Chrome will make three requests to weird hostnames that arent resolved. For example:

HEAD http://gtblynlsos/ HTTP/1.1
Host: gtblynlsos
Proxy-Connection: keep-alive
Content-Length: 0
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.13 (KHTML, like Gecko) Chrome/9.0.597.107 Safari/534.13
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-GB,en-US;q=0.8,en;q=0.6
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3

Other example weird hostnames:


Has anyone else seen this? Any ideas what's going on? I have all Chrome extensions disabled.
