Fiddler with an Asp.net site.

Fiddler is an Http monitor and it is very handy when it comes to analyze the traffic from and to your computer or more specifically if you want to list the connections made from and to your Asp.net website. It can even log and decrypt HTTPS calls. Here’s a guide on how to get it working (from Rick Strahl’s blog), basically you just have to add the following to your web.config :

<system.net>
   <defaultProxy>
     <proxy
       usesystemdefault="False"
       bypassonlocal="True"
       proxyaddress="http://127.0.0.1:8888"/>
   </defaultProxy>
 </system.net>

Where 8888 is the port where Fiddler is listening.
