No-Store: Used to tell the caches that the content may be cached but not archived. No-Cache: This value hints that the content may not be cached.

Private: This one hints that the content may only be cached in a private cache. Public: This states that the content may be cached in public shared caches. But like most meta tags, they support more than a single value for any directive and the Cache-control is no exception. Īs you can see from above, the Cache-control uses meta tags. This is the HTTP/1.1 implementation with cache-control. Store value in cache - Store an item in the cache by key. Get value from cache - Retrieve a cached item by key. Store to cache - Caches responses according to the specified cache control configuration. With just a couple of changes, you are on your way to properly getting web browsers to cache your web pages. Get from cache - Perform cache lookup and return a valid cached response when available. With HTML5 and HTTP/1.1, it is recommended that one used the cache-control implementations. If that is no longer recommended and even fails on various HTML validators, what is the correct way to do this? Cache-Control, the HTTP/1.1 Implementation Though it is no longer recommended, I have included it here for nostalgic purposes. The throwback to the days of HTTP/1.0 that was used was the Pragma directive.

However, today we will be looking at how to do this using the HTTP headers for cache control using HTML. The cache can be controlled from the server-side, from the DNS, reverse proxies, and more. There is one not-so-new way to add to the performance that is not quite used to its extent and thatâ€™s the Cache-control. The filter will first remove any existing headers for Vary, Cache-Control, and Pragma, and then will write out the appropriate headers based on the properties set in the ResponseCacheAttribute.Web developers are always finding new ways to speed up the experience for website visitors. The ResponseCacheAttribute is used to configure and create (via IFilterFactory) a ResponseCacheFilter, which performs the work of writing the appropriate HTTP headers to the response. Order int The order of the filter (from IOrderedFilter). CacheProfileName string When set, determines the name of the cache profile to use. VaryByHeader string When set, a vary response header will be written with the response.

When true, Duration is ignored and Location is ignored for values other than None. NoStore bool Determines whether the value should be stored or not, and overrides other property values.

Location ResponseCacheLocation The location where the response may be cached. Duration int The maximum duration (in seconds) the response should be cached. The attribute has the following properties, all of which are optional unless otherwise noted. The ResponseCacheAttribute is used to specify how a controller action’s headers should be set to control its cache behavior. no-cache Indicates the response must not be used by a cache to satisfy any subsequent request (without successful revalidation with the origin server). The response could still be cached in a private cache (for instance, by the user’s browser). private Indicates the response is intended for a single user and must not be cached by a shared cache. Three common directives are: public Indicates that the response may be cached. The HTTP 1.1 specification details many options for this directive. The primary HTTP header used for caching is Cache-Control.

It's held in the address space of a single process and accessed directly by the code that runs in that process. In this case, the request is never made to the web server. The most basic type of cache is an in-memory store. This can reduce the number of requests a client or proxy makes to the web server, since future requests for the same action may be served from the client or proxy’s cache. These headers specify how you want client and intermediate (proxy) machines to cache responses to certain requests (if at all). Response caching refers to specifying cache-related headers on HTTP responses made by ASP.NET Core MVC actions.
