title: SOAP, http web service requests and url
body: <p>I am familiar with http web service requests where parameters needed by the service are provided in the url query part, like ?parm=1 or ?file="C:\test.xml".  </p>
  
  <p>I am reading on SOAP at the moment and I wonder what calling technique lies behind this:<br>
  - is a SOAP request translated to a url in the background (transforming the SOAP xml into a string as part of the url query part)?<br>
  - does a SOAP request have a url equivalent always?<br>
  - or are both SOAP and http service requests translated into an http POST request in the background?<br>
  - where can I find good, clarifying examples of all this?</p>
