Suspecting Twitcher is buffering the request and/or the response which
makes Raven appears to take longer to respond to client request.

This is meant as a temporary testing setup only, NOT to be enabled
permanently on prod.

Left the code commented out so we have a sample how to do this as documentation.

Have to increase it here since this is an Ouranos prod environment
specific problem therefore not appropriate to increase in the generic
birdhouse-deploy repo.

Could not set it here due to this error:
