 * PassPhraseAgent for use in server environments.
 * You set the passphrase first by passing it a servlet request. It fetches the passphrase from the paramater "passphrase"<p>
 * <b>WARNING</b> The sequence of events is very important for the safe usage of this. The following is an example within a
 * standard <tt>doPost()</tt> method.
 * <ol>
 * <li><tt>agent.setRequest(request); // Set the request</tt>
 * <li><tt>signer.sign(data);// Sign some data</tt>
 * <li><tt>agent.clear();// The moment we have used the passphrase we have to clear it</tt>
 * </ol>
 * Note, the above assumes that a <tt>Signer</tt> with the name signer was initialised in <tt>init()</tt> with a
 * <tt>ServletPassPhraseAgent</tt> called <tt>agent</tt>.
