Write an irule or a policy to allow specific URIs

Hi Guys,   I'm quite new to F5. We have a requirement for allow only 4 specific URIs and block any other URI. What would be the best way to do it. Would it be using an irule or using a LTM policy...

use this iRule:

when HTTP_REQUEST {
	switch -glob [string tolower [HTTP::uri]]
		"/uri1*" -
		"/uri2*" -
		"/uri3*" -
		"/uri4" 
		{
			#do nothing
		}
		default
		{
			#drop others
			drop
		}
}

Thanks, I will try this, if URI contains Uppercase characters, do i need to change to it lower case in iRule? would that be matched?
