Does AMF support caching?

Question

In other words: Can I respond with a 304 and have it "just work"?

Answer 1

By default Flex's RemoteObject and BlazeDS handle AMF requests as POSTs so they won't cache in the browser. You could change that by implementing your own servlet that serializes GET responses as AMF. Then on the Flex side use URLLoader to make the request. That might cause the browser to cache the response.
