Tableschemas are downloaded by validata-ui
on demand.
To limit stress on schema providers (github.com, framagit.org, ...), module requests_cache replaces cache_control.
cache-control (current library) caches based on HTTP response headers whereas requests-cache (new library) always caches.
- schema urls are cached during a period of n minutes
- number of minutes can be set using
CACHING_EXPIRE_AFTER
env variable - default is no cache
