Description
I have a requirement that need to route request to different resource class by the 'Accept' fields in the request HTTP header.
What I think is to write a middleware with process_request that parse req.accept and change the uri of the request. Then use route to route the "real" uri to different handlers.
But it seems that the uri of the request cannot be set directly. I check the property, change the path instance variable maybe can change the uri.
Is there any elegant approach to fulfill requirement using falcon?
Thanks

Research direction
Start by reviewing Falcon's middleware process_request hook, req.accept handling, and route matching behavior. Determine whether API versioning by the HTTP Accept header has a supported routing approach without directly changing the URI, and define the expected resource-selection behavior before considering an implementation.
