• Before it was using url.pathname.indexOf(self.context.environment.key) > -1 to find fingerprinted assets, but it wasn't finding them
• Instead, it was going to the next if statement, so it was using the staleWhileRevalidate strategy for requests to /client.js?fingerprint=0270f3e40e56449d6de75b1a73e4c1d0843e6ef0 for example
• It didn't work because everything after the ?= is not part of the pathname. I logged the pathname and it only returned /client.js
• So I changed it to url.searchParams?.get('fingerprint') === self.context.environment.key to get the fingerprint param. This properly activates the cacheFirst strategy
