The goal of caching in HTTP/1.1 is to eliminate the need to send requests in many cases, and to eliminate the need to send full responses in many other cases. The former reduces the number of network round-trips required for many operations; we use an expiration mechanism for this purpose (see section 13.2 ) For example, the no-store directive must not exist in request or response header fields. See Section 3: Storing Responses in Caches of the RFC document for details. Problems with cookies. Currently it is not possible to use cookies with response caching. As soon as cookies header is present the caching of request is considered as impossible To disable the default use of HTTP header variables, complete any of the following tasks: Disable authentication source variables by setting the DisableAuthSrcVars parameter to yes. Disable user session variables by setting the value of the DisableSessionVars parameter to yes. The default is no. If you are using Controlling the cache key. With Amazon CloudFront, you can control the cache key for objects that are cached at CloudFront edge locations.

Pragma is an HTTP/1.0 header.Pragma: no-cache is like Cache-Control: no-cache in that it forces caches to submit the request to the origin server for validation, before releasing a cached copy.However, Pragma is not specified for HTTP responses and is therefore not a reliable replacement for the general HTTP/1.1 Cache-Control header. Pragma should only be used for backwards compatibility with. where date is the date in the object's server response header and last_modified is the date in the Last-Modified header. If there is no Last-Modified header, then Traffic Server uses the date the object was written to cache. The value 0.10 (10 percent) can be increased or reduced to better suit your needs.

HTTP-based caching respects request Cache-Control directives. The HTTP 1.1 Caching specification for the Cache-Control header requires a cache to honor a valid Cache-Control header sent by the client. A client can make requests with a no-cache header value and force the server to generate a new response for every request.. Always honoring client Cache-Control request headers makes sense if you. Many more directives are available - see the Feature-Policy documentation on MDN for a full list.

To modify Cache-Control directives other than max-age (see RFC 2616 section 14.9), you can use the Header directive. When the Expires header is already part of the response generated by the server, for example when generated by a CGI script or proxied from an origin server, this module does not change or add an Expires or Cache-Control header Expiration can be set on a per-session, per-URL, or per-request basis, in addition to cache headers (see sections below for usage details). When there are multiple values provided for a given request, the following order of precedence is used: Cache-Control request headers (if enabled) Cache-Control response headers (if enabled Cache-Control.

It does not cache responses with Cache-Control set to Private, No-Cache, or No-Store or with Set-Cookie in the response header. NGINX only caches GET and HEAD client requests. You can override these defaults as described in the answers below Caching full pages with response caching. The highest level of caching that we can make use of is caching of the entire page.

You can see that by yourself. Open the Network tab in your developer tools on any website and refresh it a few times
  4. a) Full page caching: At the server side, the HTML pages are divided or fragmented into small units in the form of headers, body content, footer and so on. When the page request is made, WordPress simply combines all the fragments and presents it to the user

When a consumer requests a resource representation, the request goes through a cache or a series of caches (local cache, proxy cache, or reverse proxy) toward the service hosting the resource

For example, once the duration specified by cache-control: max-age=<seconds> has elapsed the etag header will be used For more information, see Managing how long content stays in the cache (expiration).. Client IP Addresses.
