Re: Using and verifying Proxy Communication

Alexander,
Is it possible that the message means "Connection was reset"? From what you've shown, you are successfully connecting to a proxy, but when you attempt to send/receive data you get disconnected.

    Dear all,


    I am actually trying to communicate with a vendor that checks rfc2616
    rules. So I have to ensure, that I am sending my request to the proxy
    and use the host name for the vendor. Actually the communication
    doesn´t work, but I cannot verify, if my requests pass the proxy and
    end at the vendor or somewhere else within the communication.

    Do you have some hints, how to "follow" the request through the network
    (proxy and vendor server are external).

    I have added the debug log for further checks:
