Sorry I didn't reply before. I think we figured it out on IRC, but for
the record: the problem was reading past the end of the socket with
environ['wsgi.input'].read(). paste.httpserver protects against that
case for http by not letting you read past the end of the socket, based
on the value of Content-Length. If you don't send Content-Length, it
assumes 0. For https this was disabled due to reported problems, but
I'm not sure those problems are actually associated with the wrapper...
I suspect it was a red herring.
Per the discussion on IRC, it seems like you actually need to upload
content of unknown length, which requires a client that does chunking.
Then you can call environ['wsgi.input'].read(), and it'll read the
entire body (issuing 100 Continue responses until it is read). At
least, that's my impression from a quite read of the code, but there's
also a comment in the code that says that is unimplemented. If it
doesn't work, the CherryPy server should do chunked encoding.
I'm a little unclear what environ['CONTENT_LENGTH'] will be in the case
of a chunked request. Or even what it should be.
