{ Creates a read stream for the response to the given requestHeaders plus requestBody.  Use in preference to
  CFReadStreamCreateForHTTPRequest() when the body of the request is larger than you wish to be resident in memory.  Note that 
  because streams cannot be reset, read streams created this way cannot have autoredirection enabled.  If the Content-Length 
  header is set in requestHeaders, it is assumed that the caller got the length right and that requestBody will report 
  end-of-stream after precisely Content-Length bytes have been read from it.  If the Content-Length header is not set, the 
  chunked transfer-encoding will be added to requestHeaders, and bytes read from requestBody will be transmitted chunked.
  The body of requestHeaders is ignored.
