Monitor traffic to localhost from IE or. NET

Original: http://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/MonitorLocalTraffic Monitor traffic to localhost from IE Or. NET

To monitor traffic sent to http://localhost or http://127.0.0.1 from IE8 or below or the. NET Framework:

• Use your machine name as the hostname instead of Localhost or 127.0.0.1

  For example, instead of

    http://localhost:8081/mytestpage.aspx

  Go to:

    http://machinename:8081/mytestpage.aspx

• Use one of these addresses:

  -to Use the IPV4 adapter (recommended for the Visual Studio test webserver, Codename:cassini):

    http://ipv4.fiddler

  -to Use the IPV6 adapter:

    http://ipv6.fiddler

  -to use localhost in the Host header:

    http://localhost.fiddler

• Click rules > Customize Rules ... and add this code to the rules file:

  Static function onbeforerequest  (osession:fiddler.< Span class= "Typ" >session) {if (osession. Hostnameis "MYAPP"   { Osession. Host =  "127.0.0.1:8081" ;}}          /span>                

  Now, Http://myapp would act as an alias for 127.0.0.1:8081
