As described above, the 'glue' method can be implemented via one of the following ways:
The first way: Use the native Apache HTTP Daemon's AJP proxy module.
The second way: Use the native Apache Tomcat's AJP connector.
With the first method, you only need the HTTP daemon and application server, but settings are limited.
With the second method, you can obtain more settings, but you will need to download and install additional modules for the HTTP Daemon that are not included in the default package.
