Introduction
A Server element represents the entire Catalina servlet container. Therefore, it must be the single outermost element in the `conf/server.xml` configuration file. Its attributes represent the characteristics of the servlet container as a whole.
Attributes
> Common Attributes
> > All implementations of Server support the following attributes:
> > Attribute | Description
> > --- | ---
> > `className` | Java class name of the implementation to use. This class must implement the `org.apache.catalina.Server` interface. If no class name is specified, the standard implementation will be used.
> > `port` | The TCP/IP port number on which this server waits for a shutdown command. This connection must be initiated from the same server computer that is running this instance of Tomcat. Set to `-1` to disable the shutdown port. Note: Disabling the shutdown port works well when Tomcat is started using Apache Commons Daemon (running as a service on Windows or with jsvc on un*xes). It cannot be used when running Tomcat with the standard shell scripts though, as it will prevent shutdown.bat|.sh and catalina.bat|.sh from stopping it gracefully.
> > `shutdown` | The command string that must be received via a TCP/IP connection to the specified port number, in order to shut down Tomcat.
> Standard Implementation
> > The standard implementation of Server is org.apache.catalina.core.StandardServer. It supports the following additional attributes (in addition to the common attributes listed above):
> > Attribute | Description
> > --- | ---
