      Create synapse.response-source-buffer for GET and HEAD Http methods
      Parameters:
        `method` - Http Method
        `request` - Source Request
      Returns:
        OutputStream

    - #### getSourceRequest

          public SourceRequest getSourceRequest(org.apache.http.nio.NHttpServerConnection conn)
                                         throws IOException,
                                                org.apache.http.HttpException

      Create SourceRequest from NHttpServerConnection conn
      Parameters:
        `conn` - the connection being processed
      Returns:
        SourceRequest
