* support configurable encoding...

* change the pipelining mechanism so that it does not use bean properties on the tags
    as this conflicts with the latest JSP spec.

* Handle multi-part posts to allow easy posting of files or resources.
  For example:-
  
  <http:request url="http://www.foo.com/upload" action="POST">  
    <http:file name="bar.txt" uri="/xml/bar.xml"/>
  </http:request>

* Integrate the caching and timeout features that should appear in the scrape tag library
