[windows] What HTTP traffic monitor would you recommend for Windows?

I need the sniffer to test network traffic of applications developed by me for Windows and Facebook.

Basic requirements:

• display request and response
• display HTTP headers
• display the time it took to complete HTTP request

Now I'm using HTTP Analyzer. A very good tool, but it terminates with some error after 10-15 min running on Vista.

I use Wireshark in most cases, but I have found Fiddler to be less of a hassle when dealing with encrypted data.

Microsoft Network Monitor (http://www.microsoft.com/downloads/details.aspx?FamilyID=983b941d-06cb-4658-b7f6-3088333d062f)

Try Wireshark:

Wireshark is the world's foremost network protocol analyzer, and is the de facto (and often de jure) standard across many industries and educational institutions.

There is a bit of a learning curve but it is far and away the best tool available.

Fiddler is great when you are only interested in the http(s) side of the communications. It is also very useful when you are trying to inspect inside a https stream.

I now use CharlesProxy for development, but previously I have used Fiddler

I like TcpCatcher because it is very simple to use and has a modern interface. It is provided as a jar file, you just download it and run it (no installation process). Also, it comes with a very useful "on the fly" packets modification features (debug mode).
