    When my wireless  router is down, Fiddler displays this:

    [Fiddler] DNS Lookup for "www.google.com" failed. The system reports that no network connection is available. System.Net.Sockets.SocketException No such host is known

    I do NOT want that message to be displayed. I want browser's default message" connection failed " . Any ideas?

    Thank you

    As a general rule, you can't tell your browser to pretend like it's not talking to a proxy because it knows that it is. So, unless you were to literally copy the HTML of your browser's error message and return it to the client, you can't show the exact same message. (If you tried that, you'd find that, for instance, IE's error message would show in Firefox or another browser, etc).

    You can customize the error message if you like; edit the Rules > Customize Rules > OnBeforeReturningError function.

    Hello, Satya--

    Rather than asking an unrelated question on an old thread, please ask new questions on new threads.

    > DNS Lookup for "m.adnxs.com" failed

    means exactly that-- the client attempted to perform a DNS lookup for the hostname "m.adnxs.com" and the DNS server indicated that no such hostname existed.
