Excluding URL-prefixes from SW-treatment

I have a section (“/important/”) that I absolutely do not want interfered with, what’s the recommended way to handle that? Please forgive me if that has an obvious solution, I’ve never worked with service-workers (and this plugin) before.

I saw that the default route is being registered with /.*/, but I don’t see an obvious way to change this without duplicating the code.
Would I register an additional route to match my special URL prefix and then add a handler that would simply not try to cache, but always run a fetch? Or is there a way to register a route that would be excluded?
