I'm implementting a REST web service based on a MVC @Controller annotated class. I've implemented the Etag functionality with the provided Filter and I'd like to include the Last-Modified header when returning the resource representations too. I've seen that there is a LastModified interface which should be implemented by the controller, but my problem is that I want to include the mentioned header for some of the methods implementing the REST API, and I don't know how to accomplish it.
By the way, I'm using Spring 3.0.5
Please, could anybody provide some hint?
