These statements concerns me. The Content-Length header if you are sending a response of unknown length should not be set. Further, you definitely cannot return/write more response data than is specified by Content-Length. Doing so breaks HTTP and mod_wsgi will actually deliberately discard anything returned over what Content-Length specifies. Can you clarify this? Are you setting Content-Length to a value less than the amount of data you could actually return?
