SOAP 1.2
Here is a SOAP 1.2 request and response example. Content which insight [..] need to be replaced!

--------[Request]---------
POST /iMsg/TestHelloWorld.asmx HTTP/1.1
Host: 192.168.0.196
Content-Type: application/soap+xml; charset=utf-8
Content-Length: [length]

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
? <soap12:Body>
?<HelloWorld xmlns="http://tempuri.org/" />? --the body we need to extract
? </soap12:Body>
</soap12:Envelope>

--------[Response]--------
HTTP/1.1 200 OK
Content-Type: application/soap+xml; charset=utf-8
Content-Length: [length]

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">

// Usage as follow settig
//
// Host = "192.168.0.196"
// WSName = "/iMsg/TestHelloWorld.asmx HTTP/1.1"
// WSContentBody = <HelloWorld xmlns=/"http://tempuri.org//" />
//
// Description:
// We can first log on the web service location to see the call method( http://192.168.0.196/iMsg/TestHelloWorld.asmx,
// and extract the soap body part,then we can call it on our program( Be sure it's a block call!)
