46  * Uses some code from EasySSLProtocolSocketFactory.java
47  *
48  * <p>
49  * Wraps a SSLSocketFactory with a SecureProtocolSocketFactory.
50  * <p>
51  * This was designed to make HttpClient work in situations where an application is being deployed by
52  * Java Web Start. In these cases, SSL connections are negotiated by webstart implementations of the
53  * KeyManager and TrustManager. Wrapping the socket factory obtained from
54  * HttpsURLConnection.getDefaultSocketFactory allows the use of HttpClient while still leveraging
55  * Java Web Start's handling of SSL certificates
