I see lines like this in my apache usage log, but don't understand how to read them: - - [04/Nov/2011:00:30:09 +0000] "GET /media/product/3596_5084_120.jpg HTTP/1.1" 304 175 "" "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; GTB7.1; .NET CLR 2.0.50727; AskTbMPC2/"

How can I understand these lines?
