[Question] How to handle OPTIONS preflight

[Cluster2a]

Hey, I am trying to figure out, how to handle CORS, especially the OPTIONS preflight.

I tried to implement middleware that returns HTTP.StatusNoContent if an OPTIONS call is being made, but I always get a 405.

The framework is not processing the request as there is no such route.

What is the general approach to handling CORS?

Use rest.WithCors, rest.WithCorsHeaders or rest.WithCustomCors.

@kevwan, thanks a lot! I think this should be documented somewhere.
