What is WS addressing in soap?

WS-Addressing is a standardized way of including message routing data within SOAP headers. Instead of relying on network-level transport to convey routing information, a message utilizing WS-Addressing may contain its own dispatch metadata in a standardized SOAP header.

Is Rest reliable?

Reliable messaging is the guarantee that a message sent by a sending application is indeed received at the other end, and received only once. One of the most common objections against REST is that REST doesn’t offer reliable messaging.

What is reliable messaging and transaction?

What is the extensibility model of WS-ReliableMessaging?

WS-ReliableMessaging uses the extensibility model of SOAP and WSDL. WS-ReliableMessaging does not define all the features required for a complete messaging solution. WS-ReliableMessaging is a building block that is used in conjunction with other Web Services specifications and application-specific protocols…
