Re: HTTPAPI: TCP Forwarder

Hello Alexander,
What do you mean by "TCP forwarder", exactly? If you mean that it simply forwards TCP channel to a given host, then yes, the final destination will get the wrong hostname in the HTTP headers that way. This should happen with all HTTP clients, as these forwarders do not understand the HTTP protocol and therefore will not change the header information for you automatically.
Using proxy (with http_setproxy) is the correct solution. However, this will not work with a device that simply forwards a TCP channel, it needs to be an HTTP proxy instead. 

But, perhaps this is what you mean by "TCP forwarder"?

Please provide more information.

    Hello all !!


    I am using HTTPAPI for Webservices successfully for a long time. Now I
    am facing a problem with my communication using a TCP Forwarder Gateway
    for a new WebService request. Due to audit rules, I may not access an
    outside Webservice directly. Therefore I have got a TCP-Forwarder,
    which I have been using in the past for another client without any
    problems.


    Checking the logs, I can see, that the http_url_post uses the
    gateway-name and port to receive my request and hopefully forwards it
    without any changes (it is SSL encrypted). But the final destination
    seems to reject the SOAP request due to the fact, that the Host-part of
    my request doesn´t contain the final destination but my tcp-gateway.


    Is there anybody out there, who has had a similar problem and can give
    me advice ? I have been trying to use
    http_setproxy(`Gateway.com':10069) and
    http_url_post(`https://finaldestination.com': soapmessage, etc ...) to
    get it up and running, but I cannot access the WebService.


    Thanks for your help and best regards, Alexander
