The RPGist's RPG Looking for Group platform now caches information such as Locations, RPG Systems and other that are used in the Game Preferences selectors and in the Players and Group Search filters.
Both HTTP caching and server caching with Memcached were implemented. This should improve response time and the usage of mobile data for mobile users.
Actually the main goal of this implementation is to take one more step in the preparations to move the D&D 5e Spellcaster Helper from Heroku to the VM in Google Cloud where the other RPGist apps are.
Now I just need to integrate the Spellcaster Helper with RPGist Accounts, which should take some time...
