How to display localhost traffic in Fiddler while

Question

How do I display localhost traffic in Fiddler while debugging an ASP.NET application?

Answer 1

Checking the "Use PAC Script" in Fiddler Options -> Connections worked for me when using IIS Express within a corporate intranet.

Answer 2

If trying to catpure HTTPS traffic on a local machine from BizTalk using Fiddler, try using the WCF Adapter Proxy settings. I used an address of: http://localhost:8888/

Answer 3

Start Fiddler. Go to Tools--> Fiddler Options. Choose Connections tab. Check the 'USe PAC Script' option.

Now you will be able to monitor local traffic as well

Answer 4

You may use PC hostname instead of 127.0.0.1 or localhost

Answer 5

Probably the easiest way to monitor traffic to localhost is to replace "localhost" with "localhost." in the browser's URL bar. E.g.

http://localhost./MyApp/default.aspx

Answer 6

For an ASP.NET web site project:

1) Right-click the project and select Property Pages
2) Select Start Options
3) Under the Server section, click the "Use custom server" and edit the Base URL by replacing localhost with your computer's name.
