    I thought it could, but cannot get it to do anything.

    We're running Fiddler2 on the WCF 4.5 client side of a Java web service, Windows 7, Soap.

    When I turn capturing on and send a request from my client app, I'd like to see what is actually being sent to the service including the Soap envelope and any request headers.  My problem is that the headers the service is expecting do not match the headers I'm sending, particularly the Content-Type, but I have no view of the headers so I can't tell what I'm sending.

    I do see a file captured, but what's in it is meaningless to me.  When I open the Raw tab I see the mish-mash below.  Either it tells me what I already know, or nothing at all, but hasn't anything to do with the soap message or headers.  If I open the Headers tab it's just more garbage.  I can't even tell if it's looking at my client or something else!

    I've read that you have to change ports in your web.config, which I've tried - same mish-mash.  Any clues???

    I think I've got it:

    Tools > Fiddler Options > HTTPS tag > Decrypt HTTPS trafic

    I left everything else as default, and accepted the certificate.
