Domain mode

The domain mode controls the way static content is delivered and if HTTP expires headers should be set.

When the domain is set to production static content is delivered directly from the webserver's fast local copy. This copy of the data is up to two minutes old so changes to static files are not visible to the public immediately.

The development mode causes the webservers to not use the fast local copy of files. This makes it possible to see changes to static files immediately. Please note that this degrades data throughput, latency and introduces a single point of failure. Except for development purposes a domain should always be run in production mode.
