KEY CACHING CONCEPTS
CACHING
HOLD THE RESPONSE AND SERVE IT AGAIN UPON
SUBSEQUENT REQUESTS
PRIVATE CACHE
A CACHE THAT EXISTS IN THE CLIENT.
E.G. A LOCAL DEVICE OR BROWSER CACHE.
STORES DATA FOR A SINGLE USER.
SHARED CACHE
A CACHE THAT SERVES MULTIPLE USERS.
USUALLY A CACHING PROXY OR CDN.
YOU SHOULD AVOID STORING PERSONALIZED DATA.
TIME TO LIVE
THE AMOUNT OF SECONDS AN OBJECT IS
CONSIDERED FRESH.
FRESH CONTENT
CACHED OBJECT HASN'T EXPIRED YET.
RESPONSE CAN BE REUSED FOR SUBSEQUENT
REQUESTS.
STALE CONTENT
EXPIRED CONTENT THAT SHOULD BE REVALIDATED
BEFORE SERVING. IS NOT DIRECTLY REMOVED FROM
THE CACHE.
REVALIDATE CONTENT
ASK THE ORIGIN SERVER IF THE REQUESTED OBJECT
IS STILL FRESH.
