Any way to write a "catch-all" pattern?

[TTTPOB]

recently I built a small worker to 302 redirect requests to different source of package mirrors based on the url content. The package mirror has deep file hierarchy, and I need only to process the first part of the path. My current way to implement a catch-all pattern is to write as deep as 10 params. It looks really ugly and I want to know is there any elegant way to achieve this.

P.S. I know I can write a macro to generate as deep path as I want, but I want a more elegant way.

You can use or_else_any_method_async like we do in the sandbox worker here.
