I am used to analyze http traffic response times and other useful statistical informations using justniffer for linux equipped servers.
Does anybody knows about an http sniffer like justniffer for Windows server?
Wireshark will run with the windows port of libpcap (installer includes it).
Fiddler2 is a HTTP only proxy for good debugging, but more from a browser POV.
Wireshark is the nearest thing to justniffer, albeit with a GUI. It can follow and reassemble TCP streams, and decode HTTP very clearly.
Wireshark has TShark.exe commandline tool (and not only that).
You can also use Microsoft Network Monitor 3.4. If you monitor http traffic, you should check the HTTP Troubleshoot Column Layout.
NM 3.4 also has nmcap.exe to monitor frames by commandline.
There is also RawCap, that allows you to capture frames from MS TCP Loopback inteface (127.0.0.1).
