Fiddler and Windows Phone 7 emulator - redirect to proxy

Question

I am just curious - did anyone got Fiddler to work with Windows Phone 7 emulator (RTW build)? When I try working with Fiddler, I am getting a WebException when working with HttpWebRequest insances - NotFound, to be specific. WireShark works fine.

The problem I see here is that Fiddler acts as a proxy and the WP7 application I am using doesn't go through a proxy to pass the request, while WireShark works differently - it doesn't directly pass traffic through it.

There was a similar question here but in my case I would like to override the proxy settings so that the WP7 application will connect to http:/127.0.0.1:8888 as the proxy address. Since WP7 tools are based on Silverlight, is it possible to direct a HttpWebRequest to a proxy first?

EDIT: On this page (Fiddler documentation) it is stated that XDE (Windows Phone 7 emulator) should automatically pick up system proxy settings, but for some reason it seems like it doesn't.

Answer 1

As a temporary workaround for this, you can set Fiddler as a reverse proxy. The process is described here. I used the second option by creating a rule.

NOTE: You have to set the initial host (in the if statement) to the Fiddler proxy location (since the WP7 emulator can see the proxy address). The second URL is the address you want to redirect to.

It will now capture traffic from Windows Phone 7 emulator, although it will still skip some things (like downloaded images), so use this method for testing purposes only.

Here's the very simple solution that worked for me: http://blogs.msdn.com/b/fiddler/archive/2010/10/15/fiddler-and-the-windows-phone-emulator.aspx
