/**
 * KeepAliveHttpsTransport deals with the problems with the Android ssl libraries having trouble with certificates and
 * certificate authorities somehow messing up connecting/needing reconnects. Added as generic class for SE since it
 * might be useful in SE environments as well and can be used as an example to create your own transport
 * implementations.
