A Primer for HTTPR provides an illustrated overview of Hypertext Transfer Protocol Reliable (HTTPR), a protocol that provides reliable Hypertext Transfer Protocol (HTTP) packet delivery between clients and servers to enable reliable messaging between Web services.

The article explains the advantages of reliable messaging on the Web, discusses the architecture of HTTPR and its relationship to HTTP and offers examples of Simple Object Access Protocol (SOAP) messaging over HTTPR.
