However, we are trying to initiate this communication only when an ASP
page is processed via user input. We are working with 3rd party
software here and dont have much of a choice.
So it would be great if you could provide any guidance.
I really think you'd be better served asking this in an ASP group, as
this is technically server-server communication. There must be some
kind of (lib)curl functionality in ASP, but I have no experience with
that.
I'd suggest analyzing the needs of the communication as best as
possible; there must be some kind of way to get the location (url) you
are trying to access and then initiate the communication via a proper
server-side method. Sorry couldn't be any more help.
