IETF RFC 6753 PDF

This document describes how to use the Hypertext Transfer Protocol (HTTP) over Transport Layer Security (TLS) as a dereference protocol to resolve a reference to a Presence Information Data Format Location Object (PIDF-LO). This document assumes that a Location Recipient possesses a URI that can be used in conjunction with the HTTP-Enabled Location Delivery (HELD) protocol to request the location of the Target.
