Subject Re: [httpclient] Proxy and release questions.
Date Wed, 27 Mar 2002 17:14:03 GMT
I finally got the chance to test my theory and it works with JSSE1.0.2.  I added the following
to HttpConnection (sorry, I'm working on Windows today and don't have a diff tool handy):

    /**
     * Return my alternative SSLSocketFactory.
     * @return my alternative SSLSocketFactory.
     */
    public SSLSocketFactory getSSLSocketFactory() {
        return _SSLSocketFactory;
    }

    /**
     * Set the alternative SSLSocketFactory.
     * @param factory alternative SSLSocketFactory.
     */
    public void setSSLSocketFactory(SSLSocketFactory factory) {
        _SSLSocketFactory = factory;
    }

...

    /**
     * Open this connection to the current host and port
     * (via a proxy if so configured).
     */
    public void open() throws IOException {
        log.debug("HttpConnection.open()");
        assertNotOpen(); // ??? is this worth doing?
        try {
            if (null == _socket) {
                String host = (null == _proxyHost) ? _host : _proxyHost;
                int port = (null == _proxyHost) ? _port : _proxyPort;
                if (_ssl) {
                    //_socket = SSLSocketFactory.getDefault().createSocket(host,port);
                    if (_SSLSocketFactory != null) {
                        _socket = _SSLSocketFactory.createSocket(host,port);
                    } else {
                        _socket = SSLSocketFactory.getDefault().createSocket(host,port);
                    }
                } else {
                    _socket = new Socket(host,port);
                }
            }
            _input = _socket.getInputStream();
            _output = _socket.getOutputStream();
            _open = true;
        } catch (IOException e) {
            // Connection wasn't opened properly
            // so close everything out
            closeSocketAndStreams();
            throw e;
        }
    }

...

    /** My alternative SSLSocketFactory. */
    private SSLSocketFactory _SSLSocketFactory = null;

I'm using the SSLTunnelSocketFactory code from the JDC Forum link I mentioned previously.
 It
works fine with both squid (http://www.squid-cache.org/) and muffin (http://muffin.doit.org/)
proxy servers.
