worker routes in wrangler.toml

I'm having troubles understanding how routes works This works

routes = [{ pattern = "*/assetscdn/*", zone_id = "<zone_id>" }]

routes = [{ pattern = "*/assetscdn/*", zone_id = "<zone_id>" }]

This doesn't work ✘ [ERROR] Could not find zone for assetscdn

routes = [{ pattern = "*/assetscdn/*", zone_name = "<zone_name>" }]

routes = [{ pattern = "*/assetscdn/*", zone_name = "<zone_name>" }]

This doesn't work

Route pattern may only contain wildcards at the beginning of the hostname and the end of the path: <domain>/*/assetscdn/*

routes = [{ pattern = "<domain>/*/assetscdn/*", zone_name = "<zone_name>" }]

routes = [{ pattern = "<domain>/*/assetscdn/*", zone_name = "<zone_name>" }]

This doesn't works ✘ [ERROR] Invalid URL

routes = [
  { pattern = "*", zone_id = "<zone_id>" },
  { pattern = "*/*", zone_id = "<zone_id>" }
]

routes = [
  { pattern = "*", zone_id = "<zone_id>" },
  { pattern = "*/*", zone_id = "<zone_id>" }
]

This work

routes = [
  { pattern = "*", zone_name = "<zone_name>" },
  { pattern = "*/*", zone_name = "<zone_name>" }
]

routes = [
  { pattern = "*", zone_name = "<zone_name>" },
  { pattern = "*/*", zone_name = "<zone_name>" }
]

Is there an implementation difference or I'm missing something?

The top 3, with infix wildcards, are not supported

All 3? Because in my test the first one works

If you're trying to allow /assetcdn/* on all domains then it would - I'm just saying that example.com/*/assetscdn/* wouldn't be valid. Hence why the third doesn't work, I just assumed the two above were attempting to accomplish the same thing

*/ would be all domains therefore it breaks due to a specified domain Then wildcards need to be at the start (above) or the end /* You'd need to just do example.com/assetscdn/* to serve everything under /assetscdn/*

Alright this make sense for the 3rd one which is invalid, but why the first two are different?

I think I found out: https://github.com/cloudflare/workers-sdk/blob/main/packages/wrangler/src/zones.ts#L28

But I don't understand why you need zone_name if you have zone_id to get the host, or maybe I'm missing something
