HTTPSocket class - getting to the instance

First, Smalltalk is just amazing!  I
am so impressed with what it is possible to do - with practically no knowledge!

Second. Due to my lack of knowledge
I am now stuck ;-)

I am still working on the problem of
building a Smalltalk version of Wget.  I have used the HTTPClient
as my basic object and that is doing most of what I want. However, I can't
get to the HTTP Headers. I noticed that HTTPSocket does seem to offer the
headers but this is where I get stuck.

The creation methods of HTTPSocket  (i.e.
telling it which url to go to) seem to only exist on the class side.  But
the methods for getting to headers etc only exist in the instance.  I
can't work out how to create an instance of the socket and tell it which
url to go to.  All the construction methods just seem to return the
class.  

Obviously I am missing something pretty
basic. Could someone please enlighten me?
