Class NonBindingSocketFactory

java.lang.Object

io.fabric8.gateway.servlet.support.NonBindingSocketFactory

All Implemented Interfaces:

org.apache.commons.httpclient.protocol.ProtocolSocketFactory

public class NonBindingSocketFactory
extends Object
implements org.apache.commons.httpclient.protocol.ProtocolSocketFactory

A @{link ProtocolSocketFactory} implementation that does not bind a socket.

The reason for this ProtocolSocketFactory implementation is that for ProxyServlet we don't need to bind to a local address and port. This binding can cause issue in PaaS environments where restrictions apply.

When HttpConnection.open() calls ProtocolSocketFactory.createSocket(String, int, InetAddress, int, HttpConnectionParams) which by default will use DefaultProtocolSocketFactory.createSocket(String, int, InetAddress, int, HttpConnectionParams). The method that will be invoke is DefaultProtocolSocketFactory.createSocket(String, int, InetAddress, int, HttpConnectionParams) which will call return new Socket(host, port, localAddress, localPort);. The Socket.Socket(InetAddress, int, InetAddress, int) constructor will create a new Socket and connect to the remote address and port (the first two arguments). It will also bind() to the local address and port. This is the part that can cause issue in PaaS environment where there are restrictions.
