Hi.

Does any of you know a good HTTP / HTTPS packet sniffer for Windows?

I need it for debugging a webapp

I prefer open source (.NET), but shareware or paid products are also of interest.

/Thanks

What you want is a proxy. BurpProxy can do it, so can Fiddler2 (as pointed out by Si, it supports it natively, plugin available to edit the data).

Hi silky, you no longer need a plugin for Fiddler, see my link :)

Cheers Si, I assumed that you did given the note on the homepage about the external tool to do form tampering; but come to think of it that obviously implies that the traffic has been decrypted first :) Will correct.

Do you actually need packets? Both Fiddler and Firebug will show you HTTP/S traffic going back and forth from an app to a server.

If you really need to get down to the packet level, try WireShark.

For sniffing HTTPS Fiddler will help, otherwise go with Wireshark or Network Monitor for general sniffing.
