Method Detail

handleRead

public org.glassfish.grizzly.filterchain.NextAction handleRead(org.glassfish.grizzly.filterchain.FilterChainContext ctx)
                                                        throws IOException

The method is called once we have received some HttpContent. Filter gets HttpContent, which represents a part or complete HTTP request. If it's just a chunk of a complete HTTP request - filter checks whether it's the last chunk, if not - swallows content and returns. If incoming HttpContent represents complete HTTP request or it is the last HTTP request - it initiates file download and sends the file asynchronously to the client.
