Using Fiddler with Localhost traffic

Fiddler is an indispensable web application development tool.   For those who might not know what Fiddler is, it is a tool that allows you to see the complete request and response between your browser and the web server.    

I am afraid that many developers may dismiss it as useless when they are trying to troubleshoot .Net development because it doesn’t show the traffic between the the web browser and the development web server that listens on localhost.

While this page has a few solutions to the problem.  The solution can be solved easily by adding  a period after “localhost” in your URL.

Instead of http://localhost:1234/MyApp/…,
use http://localhost.:1234/MyApp/… ( notice the extra dot after localhost).

sometimes the little changes make all the difference.

UPDATE:   Another solution would be to use the Hostname of your machine instead of “localhost”.
