This folder is meant to experiment with HTTP caching behavior for https://issues.apache.org/jira/browse/SLING-9655 which is meant to implement caching of GraphQL query results at the HTTP level.

To start the caching service container image use

docker build -t cache .
docker run -it -p 8080:80 cache

And you can then experiment with requests like the following to see what's being cached or not:

export P=max-age
for i in 1 2 3 4 5
do
  curl -D - "http://localhost:8080/${P}.lua"
  sleep 2
done

Which should show the same cached content (“max-age=5 at ”) for 5 seconds and then another timestamp for 5 seconds, etc.

Using the private path instead of max-age shows no caching.

TODO: add examples of request revalidation.
