Java NIO HTTP server and Browser

Question

I coded a small server with NIO while walking normally except that the server can not make broadcasts at certain times to my clients because of the closure of the channel. Is there a solution against this problem? I make http requests via the browser.

Thank you for your help. Cordially.

The simple answer is yes, you can keep the socket open. I don't know why you feel you need to close it. BTW nice pic. ;) — Peter Lawrey

Thank you for your response, I wish to make HTTP requests, if I close the socket I get my answer if the application runs in a loop so I'm forced to close the socket. The problem is that after the server can not make broadcasts with new updated information to my clients — user2444092

Your browser must support persisted HTTP 1.1 connections. If it does you can keep the connection open and the browser can reuse it many times. If you browser is not using these persisted connection you have no choice but to close the connection as this is what the browser expects. See en.wikipedia.org/wiki/HTTP_persistent_connection for more details. — Peter Lawrey

private static void channelWrite(SocketChannel channel, ByteBuffer writeBuffer) { long nbytes = 0; long toWrite = writeBuffer.remaining(); try { while (writeBuffer.hasRemaining()) { channel.write(writeBuffer); } channel.close(); } catch (ClosedChannelException cce) { infos("problème"); } catch (Exception e) { } // get ready for another write if needed writeBuffer.rewind(); } — user2444092

You can take a look into Comet technology. Of course you browser should support Http1.1 keep-alive
