glob

Find files matching a glob pattern, routing by path prefix.

Routes to backends based on path: a routed path searches that route, "/" or None searches every backend, and a non-route path searches only the default backend.

When merging across routes, a pattern that targets a route is rewritten relative to that route's internal root (see _strip_route_from_pattern); a bare pattern is forwarded unchanged and matches recursively within every route; and a root-anchored pattern that targets no route skips the routed backends entirely, since their results are always deeper than the anchor permits (see _route_glob_pattern).
