Acquire Method
This is a skeleton class that implements most of the functionality
- of a method and some usefull functions to make method implementation
+ 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
