[Acronym] for __S__imple __O__bject __A__ccess __P__rotocol.

It's a way for a computer program to call a function on another computer, a concept known as [RPC]. Previously known [RPC] implementations have always been somewhat platform and/or language specific. [SOAP]'s answer is to use [XML] for [Serialisation] in marshalling the call and [HTTP] to transport it. In other words: [SOAP] is a bloated, over engineered implementation of a perfectly trivial concept. Sigh.

The canonical [SOAP] service is a WebServer at [IBM] which returns (delayed) stock quotes.

This Wiki has a [SOAP] source letting you grab the wiki source of a webpage. There's a [WSDL] file [describing this source | http://www.wlug.org.nz/phpwiki/soap.wsdl], and you can use [xmethods.net | http://www.xmethods.net/] to get [a human readable version of it | http://www.xmethods.net/ve2/WSDLAnalyzer.po;?wsdlurl=http%3A%2F%2Fwww.wlug.org.nz%2Fphpwiki%2Fsoap.wsdl].

See also [AXIS].

> Anyway, I tested this proxy by connecting my [IRC] client to it. It worked perfectly, albeit rather choppily, as the stream was being broken up into lots of little [XML] documents, turned into [HTTP] requests and then being reconstituted at the other end of the tunnel.
