Recache
Recache is a transparent cache solution for the Reve Ruby EVE API gem.
CCP’s servers are hardly forgiving in their cache management, and in any case local caching reduces the load on them. In a web application, caching can be invaluable for external services.
Recache is a drop-in Rails plugin to implement a transparent cache layer. That is, you just reference the Recache module instead of Reve and everything works exactly the same.
