//
// AUTHOR: Peter Hunter, on the basis of work by Scott Kurowski (v3 API)
// Michiel van Loon, OS/2 adaptations
// Kurowski 5/1998, 4.0 API support for MPrime 16.x
// Kurowski 9/1999, 4.0 API changes for MPrime 19.x
// Woltman 1/2002, Windows support and bug fixes
// Woltman 10/2005, Version 5 API support, CURL library
// Woltman 9/2017, Added interim residues to AP msg, added PRP support
// Woltman 9/2019, Added PRP dblchk support
// Woltman 6/2020, Added PRP Proof support, removed sockets support
//
// ASSUMPTIONS: 1. less than 4k of data is sent or received per call
// 2. HTTP/1.1
// 3. PrimeNet Version 5 or later API on server and client
