What is browser cache and proxy cache?
Proxy server caching differs from browser caching in that website resources are stored in intermediate servers, instead of on your visitors’ local drives. While a browser cache is almost completely controlled by a user, and can be deleted or modified at will, proxy server caching occurs on the CDN side.
How does web cache work?
Web caching works by caching the HTTP responses for requests according to certain rules. Subsequent requests for cached content can then be fulfilled from a cache closer to the user instead of sending the request all the way back to the web server.
How is cache control used in the browser?
Cache-control is an HTTP header used to specify browser caching policies in both client requests and server responses. Policies include how a resource is cached, where it’s cached and its maximum age before expiring (i.e., time to live). The cache-control header is broken up into directives, the most common of which are detailed below:
How is the process of caching a website governed?
The process is governed by a browser’s internal cache policy, which indicates the resources that are to be cached and for what period of time. As a website owner, you have some amount of control over this policy through HTTP cache headers, namely the Cache-Control and Etag headers.
How is the cache-control directive used in caching?
To specify the time for which the content can be cached, Cache-Control has a max-age directive. It defines a relative time in seconds for which the content can be cached. The directive below allows the content to be cached for 1 hour or 3600 seconds. If a response contains both the Expires header and the max-age directive, max-age takes precedence.
