    The server we use requires <proxy usesystemdefault="False" proxyaddress="http://10.50.131.50:8080"/> for the WebRequest to reach the 3rd party site I'm trying to get files pulled down from.  On that server Fiddler2 will capture traffic if I use a browser to pull the files, but if I use my application it will not.  I am a Fiddler2 novice, BTW, so I've just tried what looked relevant which is in Tools/Fiddler Options I put 8080 for the Fiddler listens on port on the Connections tab and I also tried on the Gateway tab setting it to Manual proxy https://10.50.131.50:8080 like the proxy setting in my app.config file.  Neither of those do it.  I found that if I remove the proxy setting from my app.config file then Fiddler2 sees the calls my application makes, however, as stated above, the calls do not reach the website so that doesn't help much.

    Being a newbie I have reached the limit of things I can see to try ... can anybody help?

    Hello David,

    Fiddler itself is a proxy so in this scenario you have to chain proxies. I.e. your app -> Fiddler -> 10.50.131.50:8080  . From your post I take it that your app is configured to use 10.50.131.50:8080 directly as a proxy effectively bypassing Fiddler. You should point your app proxy setting to Fiddler and then tell Fiddler to use 10.50.131.50:8080 as a proxy.
