/**
 * This socket factory holds secure socket factory parameters. Besides the usual
 * configuration mechanism based on setting JavaBeans properties, this
 * component may also be configured by passing a series of attributes set
 * with calls to <code>setAttribute()</code>.  The following attribute
 * names are recognized, with default values in square brackets:
 * <ul>
 * <li><strong>algorithm</strong> - Certificate encoding algorithm
 *     to use. [SunX509]</li>
 * <li><strong>clientAuth</strong> - Require client authentication if
 *     set to <code>true</code>. Want client authentication if set to
 *     <code>want</code>. (Note: Only supported in the JSSE included with 
 *     J2SDK 1.4 and above.  Prior versions of JSSE and PureTLS will treat 
 *     'want' as 'false'.) [false]</li>
 * <li><strong>keystoreFile</strong> - Pathname to the Key Store file to be
 *     loaded.  This must be an absolute path, or a relative path that
 *     is resolved against the "catalina.base" system property.
 *     ["./keystore" in the user home directory]</li>
 * <li><strong>keystorePass</strong> - Password for the Key Store file to be
 *     loaded. ["changeit"]</li>
 * <li><strong>keystoreType</strong> - Type of the Key Store file to be
 *     loaded. ["JKS"]</li>
 * <li><strong>protocol</strong> - SSL protocol to use. [TLS]</li>
 * </ul>
