You are not supposed to use a secure socket factory here, because the
job of ProxyClient is to set up a plain text connection with the proxy,
which can be used to tunnel any _arbitrary_ protocol, not just SSL.
Here's what you are supposed to do
(1) Request a plain connection to the target host via the proxy
hostConfiguration.setHost("myhost", 443);
(2) Establish a connection to the proxy
ProxyClient.ConnectResponse response = proxyClient.connect();
if (response.getSocket() != null) {
// tunnel SSL via the resultant socket
SSLProtocolSocketFactory sslSocketFactory =
new SSLProtocolSocketFactory();
Socket sslsocket = sslSocketFactory.createSocket(
response.getSocket(),
"myhost", 443, true);
} else {
// say oopsie
}
(3) You are done
