Hello Experts,
As you know, we already support filters as well as a few different ways in which they can be bound to resource classes and methods (by name or global/static or dynamic). However, all these filters are intended to be executed _after_ requests are matched to resource methods.
There are some use cases in which requests need to be transformed _before_ the matching algorithm kicks off. An example of this is a filter that overrides the HTTP method, e.g. using X-HTTP-Method-Override. In a servlet environment, this could be achieved by using a servlet filter. But, of course, JAX-RS runs on many other environments.
Should we look at supporting these type of pre-matching filters/transformers/routers? (Clearly, I don't have a good name for them yet).
