* Routes the request to the requested deployment.
|
|
*
|
|
* A specific deployment can be requested via:
|
|
* - the `dpl` search parameter for assets
|
|
* - the `x-deployment-id` for other requests
|
|
*
|
|
* When a specific deployment is requested, we route to that deployment via the preview URLs.
|
|
* See https://developers.cloudflare.com/workers/configuration/previews/
|
|
*
|
|
* When the requested deployment is not supported a 400 response is returned.
|
|
*
|
|
* Notes:
|
|
* - The re-routing is only active for the deployed version of the app (on a custom domain)
|
|
* - Assets are also handled when `run_worker_first` is enabled.
|
|
* See https://developers.cloudflare.com/workers/static-assets/binding/#run_worker_first
