Answer 1

One useful variation of Eric's answer (that was edited by Brett) would be to use oSession.port to build the oSession.host. With this little change, if one needs to capture IIS express traffic on http://localhost:12345, they could use http://iisexpress:12345. That will make it easier to capture traffic for sites with random ports as created by WebMatrix and VS. I tried it out with IE and Firefox and capturing IIS Express traffic was a breeze. Fiddler rocks!.

static function OnBeforeRequest(oSession:Fiddler.Session)
{
   //...
   // workaround the iisexpress limitation
   // URL http://iisexpress:port can be used for capturing IIS Express traffic
   if (oSession.HostnameIs("iisexpress")) { oSession.host = "localhost:"+oSession.port; }
   //...
}
