            The <span class="code">GlobalContext</span> provides a location for global debugging 
            information to be stored.
            </p><p>
            The global context has a properties map and these properties can 
            be included in the output of log messages. The <a href="T_log4net_Layout_PatternLayout.htm" target="">PatternLayout</a>
            supports selecting and outputing these properties.

            By default the <span class="code">log4net:HostName</span> property is set to the name of 
            the current machine.
