we are getting "A LOT" of requests from one particular IP address. I turned
on the access log to see what's what, and this is what I see repeatedly
(i.e. thousands of times - like its in a loop):

168.9.38.5 - - [20/Oct/2009:10:53:43 -0500] 200 "GET / HTTP/1.0" 23201 "-"
"Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR
1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648;
InfoPath.2; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)" "10.9.5.171,
127.0.0.1"

Does anyone know what this may be?

Thanks
