Secondary machine components
In a multiple-machine deployment, you deploy FileMaker WebDirect secondary machines that include only two components: a web server and the Web Publishing Engine.
The primary communicates with the secondary to configure the settings on all machines and monitor the status and activity of all components.
The Custom Web Publishing services and the PHP engine are on the primary machine. However, a secondary machine can handle Custom Web Publishing requests from users because it provides routing services. For best results when hosting solutions that use Custom Web Publishing with PHP, put all the PHP webpage files in the appropriate FileMaker hosting folders (htdocs) on the primary machine and on all secondary machines.
Important To enhance the security of your database solution, especially when it is available on the internet, use a firewall with your FileMaker Server deployment. Also use SSL for the web server. See FileMaker Security Guide.
