Thanks Ts. Still not sure. Please read below:

Can I omit this ::? Is it valid to omit it? or it has a "namespace" impact? 
When should I use :: at top level?

>S> - define_http_method_interface :PropFind, true, true

What is a symbol? what is the difference between symbol and variable? Can 
you tell me where in the document I can find the usage of symbole and :name 
notation?

It seems HTTP#get is a class method? or if not? what is the symbol # mean, 
in method definition?

Tks.
