An endpoint reference (EPR) is a combination of Web services
(WS) elements that define the address for a
resource in a Simple Object Access Protocol (SOAP) header. In this
context, an endpoint is any user device connected to a network.
Endpoints can include personal computers (PCs), personal digital assistants (PDAs) and specialized
equipment such as inventory scanners and point-of-sale
terminals.
An EPR consists of a Uniform Resource Identifier (URI), message
reference parameters and data concerning the interface to be
used. The EPR may also contain a set of policies relevant to the endpoint such as its intended
behavior and capabilities. An EPR allows the sender to tailor a message to meet specific needs.
Common examples include "reply-to" and "from" addresses that the recipient can use for authentication,
response or acknowledgment of receipt.
