Express.js close response

Question

Is there a way to close a response? I can use res.end() but it doesn't actually close the socket.

What I want to achieve: I am writing a Java program which interfaces with the network, and I am writing a node.js server for this. Java code:

String line;
while((line = in.readLine()) != null) {
    System.out.println("RES: "+line);
}

But this just keeps hanging.. No end connection, still waiting for input from the socket.

Node:

exports.getAll = function (req, res) {
    res.set("Content-Type", "text/plain");
    res.set(200);
    res.send(..data..);
    res.end();
}

however res.end() does not close the connection.. As said before, java keeps thinking there will be something next so it is stuck in the while loop.

Thank you

Answer 1

Solved by setting a HTTP header to close the connection instead of default keep-alive strategy.

res.set("Connection", "close");

Answer 2

In case someone who really wants just to close the connection finds this, you can use res.socket or res.connection to get the net.Socket object which comes with a destroy method:

res.connection.destroy();
