Server method enhanced caching support

[hueniverse]

Server methods can be used as prerequisites and handlers. However, caching these methods is not possible if they return a stream or other non JSONifiable response.

The steps are to:

• enhance catbox to support caching of streams
• allow caching of delayed execution (e.g. method returns a stream, which is cached later after the stream is finished piping)
• link cache policy with the HTTP response (cache-control and warning headers)

This issue replaces #1237, #1243, #1250, #1263

Is there any progress on this topic (or a rough plan when this issue will be addressed)? I'd love to use catbox-s3 directly via hapi configuration.

[hueniverse]

Nope. I doubt it will make it into v8.0.

Any chance this will be added to the 9.0.0 milestone? Or might this make its way in before 9.0.0 since it may not require any breaking changes?

I am not actively working on this but I'm also not inclined to put a help wanted label on it because I am unlikely to like other people's implementation for this :-). But if someone wants to give it a go...

Any update on this?

Second that, would also be interested for caching streams which are currently just piped through the reply interface. Its a while since the issue got created so it would be good to know from @hueniverse if there is is some progress or additional thoughts about an implementation.

It's a feature I want to add but have no time or need for at this point. If someone wants to give it a try, I'm open to it, but historically, I've been pretty hostile to other people's code when touching these areas of the framework. If you really want to do it, start with catbox.
