9. Utilize browser caching
Date: 24/05/2017
Status
Accepted
Context
We needed to make sure we're not overloading the servers with excessive requests. We wanted to find a way to serve fresh resources while keeping the back-end happy.
Decision
Page Previews will leverage the browser's cache rather than maintaining its own. We rely on Grade A browsers implementing HTTP caching correctly and their vendors making accessing them as efficient as possible in order to avoid incurring the incidental complexity of writing our own cache in JavaScript.
We'll set appropriate Cache-Control HTTP headers for both the MediaWiki API,
via the maxage and smaxage main module parameters, and the RESTBase page
summary endpoint with the help of the Services team.
Consequences
Resources fetched from the MediaWiki API will be cached for 5 minutes in public caches and the browsers's cache. Unlike the MediaWiki API, resources fetched from the RESTBase endpoint, will be cached for 14 days in public caches.
