RE: [wsrp-wsia] [I#187] How does POST data reach the Producer

[Gil Tayar <Gil.Tayar@webcollage.com>]

Actually, in servlets, its very easy to get the body of the request - use
request.getInputStream() and request.getContentType(). Also, determining
which parameters in request.getParameter*() are query parameters and which
are form parameters is an almost impossible job!

As for Andre's use case - nothing stops the portal from sending binary _and_
parsing the data. I just don't think that the spec should deal with it as
_the_ use case for POST. From the specs point of view, this is payload.
Anything else will risk compatibility with future browsers. For example,
what will happen when browsers move to XForm submission? In XForms the data
is not name/value pairs, but rather XML. So, should it be in uploadData or
in the field reserved for the form name/value pairs? If we have only
"payload", we don't even have to answer that question.

I believe Andre's use case is a common one, and I don't think consumers 
can always send the of the body of the request data as is without ever 
parsing it. Why force consumers to always recreate the body?
