Koji This is how non-blocking I/O works. If the underlying I/O session is unable to accept any more input the write operation returns immediately with zero bytes written instead of blocking the thread. Once the I/O session can accept more input it will trigger #produceContent event again and the producer can produce more data. Please take a look at data producers shipped with the library as reference. Hope this helps Oleg > To illustrate this issue, I wrote a simple test case which POST data > via HTTP and HTTPS.
