I'm working on a prototype where I hide the HttpServletRequest/Response
objects and the various servlet goo-age behind HttpRequest/Response.
Imagine that a servlet is calling out to a handler of a "service(...)"
where the parameters are HttpRequest/Response, populated by the servlet
prior to calling this handler. I'm looking for best practices to do this,
based on the design of the HttpCore classes and the expectations of
clients that receive HttpRequest/Response objects. I've done
"TheGuidedTour..." and read some Javadoc.
Todd,
The guided tour is somewhat outdated. There is a more recent and more
complete document describing HttpCore API and its intended usage:
http://hc.apache.org/httpcomponents-core/tutorial/html/
http://hc.apache.org/httpcomponents-core/tutorial/pdf/httpcore-tutorial.pdf
I'll look into your questions tomorrow in details and try to give you
some recommendations. However, I just cannot help wondering what it the
reason for trying to put HttpCore on top of a Servlet based transport?
While HTTP headers may be relatively easy to map, content streaming may
be significantly more difficult to achieve without a certain performance
degradation.

HttpServletRequest headers: These seem straightforward enough - I just
copy these into the headers of the HttpServletRequest.
HttpServletRequest parameters: Based on my reading of "GuidedTour..." I'm
guessing that stuff this parameter map into some HttpParams derivation
associated to the HttpRequest, and document the well-known key?
HttpServletRequest other data : Likewise, I stuff this data into
HttpParams (either Basic or a specialized derivation)?
ServletRequest host info : I grab this data, put it into an HttpHost
object, and associate it to the HttpRequest's HttpContext?
In dealing with the HttpResponse when shipping this data back out through
the HttpServletResponse, I think I'm going to want to run the responses
interceptors as well as checking headers. If both a header and an
interceptor for that header is defined, it looks like I should err-out,
rather than prefer one over the other?
