How to make Fiddler listen to a website on port 81?

Question

Is it possible to make Fiddler capture traffic for a website on port 81 using IIS7

Answer 1

Sure - Fiddler will capture all traffic going through WinINET. You can also capture localhost traffic if you use http://ipv4.fiddler:NNN as your server instead of http://localhost:NNN (where :NNN is the port that you're connecting to).

I don't believe (or at least I haven't found a way) to have Fiddler only capture a specific port for a specific host (like capturing only port 81 on localhost instead of capture all port traffice on localhost).

HTH!

Answer 2

If your site is running on your local machine (127.0.0.1) take a look at the Fiddler Network configurations about
