Subject SO_LINGER option
Date Fri, 11 Feb 2011 10:48:25 GMT

I see it is possible to set the SO_LINGER option by calling

    HttpConnectionParams.setLinger(params, so_linger);

However, from looking at the docs and specification I find that it is not possible to enable
SO_LINGER and set it to 0 at the same time. This should force immediate shutdown of a socket
upon close(), according to the spec in java.net.SocketOptions. But HttpClient treats 0 as
disabled linger. As far as I understand, disabled linger is different from enabled linger
with 0. How can I enable linger with a timeout of 0?

For more info consider:

The implementation in HttpClient is in the class DefaultHttpClientConnection.bind():

        int linger = HttpConnectionParams.getLinger(params);
        if (linger >= 0) {
            socket.setSoLinger(linger > 0, linger);


Kind regards, Roman
