How to block a specific URL

I hope it's not bad form to jump in here but I have a follow-up question to this discussion ...

 

 

In Bhattman's suggestion about using multiple patterns in a "switch" command, what would happen if the switch command could not match any of the patterns? Would it allow the connection to proceed? I've read up on the "switch" command and see that there is a "default" keyword so that you can specify what you want to happen if it can't find a match. But, what happens if you don't explicitly specify a "default" action? In my case, I want to drop (or reject?) the connection if the URI matches or contains any of three strings; otherwise, the connection should be allowed.

 

 

Thanks in advance for any guidance you can offer!
