   I missed Scott's reply because I thought I'd found the solution with
   the proxy parameters in the CFGHTTPSCH

   Command on Friday night, and because of the switch from April to May
   posting groups. It now works and I have the full sockets document
   sitting happily in the ifs. Simple when you know how.



   One of the problems with forums is that we have to expose our
   ignorance every time we ask a question. In the early days of learning
   a subject area it's all anarchy until we can amass enough facts and
   concepts such that they intersect and start forming a pattern. My
   stumbling across forward proxy settings in that command, and
   references to the administration server were cul-de-sacs. The concept
   of setting the 'pointer' to a proxy made sense to me at my current
   level of knowledge. That any request to got outside our network would
   then pass control to the proxy seemed a sensible idea. It never
   occurred to me that we would have to explicitly set something in the
   application code as that would mean it would have to be done every
   time the program ran or we wanted a new process. Surely a universal
   configuration setting is better than a run-time command repeated ad
   nausea? That's not a criticism of Scott's code. There is probably a
   technical reason why it's being done at a code level that I'm not
   aware of at the moment.



   I understand the concept of a client and a server, and that any
   request is a client request that is answered by a server which
   provides a response. What I've been uncertain about is how the client
   makes the request. Because this is all under the HTTP banner, I
   thought that there might be APIs that are provided by the HTTP Server
   to go out. I have a feeling that this is not the case and that
   requests are made via TCP using sockets?



   So I put example1 into debug and tracked down through the calls. I
   found all the procedures provided by the httpapir4 service program but
   came to a dead-end at comm_BlockWrite. I presume this is located in
   one of the modules or service programs  used by the service program,
   and that I don't have access to any of that source code.



   I suppose what I need to learn is what all of the HTTPAPIR4 exported
   procedures provide and how they are used in practice.



   Thanks again.
