Hey, I'm trying to use this pattern: "(?:www\.)?shop\.example\.com/collections/:handle([^/]+)" to match these urls: https://shop.example.com/collections/new-arrivals https://www.shop.example.com/collections/fall-2018 but not this url: https://othersubdomain.shop.example.com/collections/new-arrivals Unfortunately, if use a non-capturing group, somewhere in the pattern cleaning process, the ":" character confuses the framework. If I use a normal capturing group: "(www\.)?shop\.example\.com/collections/:handle([^/]+)" still doesn't work because it gets confused with the _handle_ parameter
