You can follow 2 approaches.

Neagtive Security - Allows everything, and reject what I know

when HTTP_REQUEST {
	 switch -glob [HTTP::uri] {
                "/" -
		"/abc"
		{
                      reject
		} 
		default {
		       return
		}
	}
}

Positive Security - Rejects everything and allow only what I know

when HTTP_REQUEST {
	 switch -glob [HTTP::uri] {
                "/123*" -
		"/234*"
		{
                    return
		} 
		 default {
		        drop
		}
	}
}
