- Cache-Control header - HTTP | MDN - MDN Web Docs
max-age The max-age=N request directive indicates that the client allows a stored response that is generated on the origin server within N seconds — where N may be any non-negative integer (including 0)
- Whats the difference between Cache-Control: max-age=0 and no-cache?
max-age=0 means that the response is immediately stale, and must-revalidate means that it must not be reused without revalidation once it is stale — so in combination, the semantics seem to be the same as no-cache
- Cache-Control - Expert Guide to HTTP headers
Response directives max-age The max-age directive is sent by a server to indicate that the HTTP response will remain fresh for a specified number of seconds after it is generated Essentially, it informs caches how long it will remain fresh
- HTTP headers | cache-control - GeeksforGeeks
The HTTP header Age defines the times in seconds of the object that have been in the proxy cache Usually, the age header is close to zero It is just summoned from the server, used to calculate the proxies' current date and the date It is a response header Syntax: age: <delta-seconds> Direc
- What is the Cache-Control Header and How to Use It
cache-control: public, max-age = 630244545; s-maxage This is specific for shared caches such as CDNs, indicating how long the resource can be served from those caches This directive will overwrite Max-Age only in shared caches if both have been set, whereas clients will only respect Max-Age values Is stale? ETag (with If-None-Match by clients)
- What is Cache-Control and How HTTP Cache Headers Work - Imperva
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:
- Cache-Control: Cheat Sheet. - shayy. org
The code snippet below sets caching rules for the response It allows any cache to store the response (public) The response is considered current for 24 hours when cached by a browser (max-age=86400), and for 2 hours when stored by shared caches, such as CDNs (s-maxage=7200)
- Does `Age` have to be used when using `Cache-Control: max-age`?
The max-age=N response directive indicates that the response remains fresh until N seconds after the response is generated Indicates that caches can store this response and reuse it for subsequent requests while it's fresh
