SOAP Routing

Routing is a process of delivering messages through a series of nodes or intermediaries. Each intermediary not only provides a message delivery channel, but may also provide value-added services such as logging, auditing and validations. Routing is an essential part of distributed computing, and will play an important rule in multi-party message exchanges. 

WS_Routing is a protocol that defines how SOAP messages can be delivered using various transports. Routing information is carried from one intermediary to another inside the SOAP header element. WS_Routing , thus, can be understood as an extension to SOAP.

SQLData WS_Routing Service

The service is available at http://soapclient.com/SoapRouter with the following features:

• It is an intermediary that supports routing to both routable destinations and non-routable destinations. Routing message can be sent to web services that don't understand WS_Routing protocol.

• All web services on this web site are routable services. i.e., routing message will be handled according to the WS_Routing specification.

A Sample Message

The following message accesses the getTemp method hosted at http://xmethods.net, it is to be routed through three intermediaries:
