I have a wildcard Cert and need to direct any sub domain name that does not exist to a custom 503 error page and don’t want to use the Frontend’s Error files feature nor its default 503 page. I want my Backend’s to handle all error pages, but on the server side.
I see in the Access Control lists / Table / Expression has Host regex, Path regex, Url parameter contains. Which one can I use to provide me the ability to check if there is a sub name or chars for example a user type in, (asdas, about, help, etc,…).kohanyim.com.
And if so, I’m really rusty on my regex syntax and can you provide examples I can use?
Would very much appreciate it, Thanks!..
