Why isn't fiddler capturing request when invoking XMLRPC from iis?

Question

I have a webapplication written in .NET, that utilizes CookComputing.XmlRpcV2 for xmlrpc-communication.

When I invoke my unit-tests in Visual Studio 2008, fiddler2 captures the actual xmlrpc-requests successfully, but when I'm running the actual application under IIS7 it shows nothing. I have verified that it actually invokes the xmlrpc-requests in my firewall, but I need to see the content of the requests for debugging purposes.

I have issued an iisreset with fiddler running in an attempt to see if IIS actually fetches proxysettings from WinINET upon app-start, but it didn't help.

Do IIS have it's own proxy-settings per app? Or if it's part of ASP.NET... I can't seem to find any information about it.

I could of course define my own proxy-server in the WebRequest somehow in code, but since I just want to utilize the proxy for debugging purposes, I'd rather find a simpler solution.

This is Vista, running iis7 with .NET 3.5 SP1. Fiddler2 version 2.1.9.2

Answer 1

The default proxy setting is per user. What identity is IIS running under?

Answer 2

Check out the answer to Setting Registry Key For All Users In C#. It refers to http://www.pctools.com/guides/registry/detail/1147/ which suggests creating a ProxySettingsPerUser registry setting and with a 0 DWORD value.
