Motivation: The HttpObjectAggregator always responds with a 100-continue response. It should check the Content-Length header to see if the content length is OK, and if not responds with a 417. Modifications: - HttpObjectAggregator checks the Content-Length header in the case of a 100-continue. Result: HttpObjectAggregator responds with 417 if content is known to be too big.
