+ * Valve that attempts to force MS WebDAV clients connecting on port 80 to use
+ * a WebDAV client that actually works. Other workarounds that might help
+ * include:
+ * <ul>
+ * <li>Specifing the port, even if it is port 80, when trying to
connect.</li>
+ * <li>Canceling the first authentication dialog box and then trying to
+ * reconnect.</li>
+ * </ul>
+ * To use this valve add the following <code><Valve
+ * className="org.apache.catalina.valves.MicrosoftWebdavFixValve" /></code>
+ * to your <code>Engine</code>, <code>Host</code> or <code>Context</code> as
+ * required. Normally, this valve would be used at the <code>Context</code>
