    Acquire Method
 

+   This is a skeleton class that implements most of the functionality
+   of a method and some useful functions to make method implementation
+   simpler. The methods all derive this and specialize it. The most
+   complex implementation is the http method which needs to provide
+   pipelining, it runs the message engine at the same time it is 
+   downloading files..
