1. Yes, tomcat is sending the header: "Transfer-Encoding: chunked" 2. I've also tried using close() instead of flush() and I've seen the same chunked encoding. 3. The nginx reverse proxying with the HttpProxyModule only supports HTTP/1.0 according to the "Synopsis" section here: http://wiki.nginx.org/HttpProxyModule
Based on my reading of the HTTP spec, closing the connection seems to be a valid alternative to sending the terminating "0\r\n\r\n". Any ideas about why the connection wouldn't be closed when using APR?
