Capturing gzipped output, and reusing.

I’m hoping to capture Javalin’s gzipped response (after, or in parallel to the response being streamed the client), and pipe it to Redis so that it can be used to serve a cached response on the subsequent requests across all nodes we’re running Javalin.

The usage pattern would preferably look something like this:

Start

1. Fetch from cache

If cache value not present (a):

1. Execute regular handler
2. Send response via standard ctx.json()
3. Stream or capture gzipped response, forward to redis (via .after handler?)
4. END

If cache value present (b):

1. Pipe Redis’ cached gzip bytes straight to the client
2. END

Where should I be looking in the framework to get the gzipped response (4a), and to stream a prebuilt gzipped response to the client from the server, via a byte stream (2b)?

I’ve not yet had a chance to get to this. Hoping to create a proof of concept sometime starting early next week.

I’m going to close this issue now, but please feel free to post an update when/if you have one.
