Description: SOAP, or the Simple Object Access Protocol, is a protocol designed to help Web applications send messages to each other. It\'s got a very simple, portable structure, based on XML, and it can travel via HTTP, so it\'s lightweight and easy to implement, plus it\'s independent of language and platform. And thus the \"Simple\" part of the acronym, without which we\'d now be learning about \"OAP,\" which isn\'t nearly as puntastic.
