#9416 3383021 Thanks @matthewdavidrodgers! - Adds support for static routing to Workers Assets
Implements the proposal noted here #9143
In brief: when static routing is present for a Worker with assets, routing via those static rules takes precedence. When a request is evaluated in the Router Worker, the request path is first compared to the "asset_worker" rules (which are to be specified via "negative" rules, e.g. "!/api/assets"). If any match, the request is forwarded directly to the Asset Worker. If instead any "user_worker" rules match, the request is forwarded directly to the User Worker. If neither match (or static routing was not provided), the existing behavior takes over.
As part of this explicit routing, when static routing is present, the check against Sec-Fetch-Mode: navigate (to determine if this should serve an asset or go to the User Worker for not_found_handling) is disabled. Routing can be controlled by setting routing rules via assets.run_worker_first in your Wrangler configuration file.
