Info

Akamai Image Manager (IM) backed service using a custom API, devoid of Akamai specifics. The purpose of a decoupled implementation is to provide portability. The API also provides backwards compatibility with the now deprecated Heroku Image Proxy service. The current implementation transforms the incoming URL parameters to an imquery that is passed on to the default IM policy. All configuration is made in a single property and policy, as the previous solution of having multiple policies (instead of using a single policy with imquery enabled) proved unnecessarily cumbersome.
