Page Caching

[OutputCache (Duration = VaryByParam = "Productno;brand;years")]

The above code declares the page cache using the @outputcatch directive, which is cached for 300 seconds. The @OutputCatch directive includes 10 properties that allow you to cache settings for different scenarios of the page, and the common properties are as follows:

CacheProfile: Gets or sets the outputCacheProfile name.

Duration: Gets or sets the time that a cache entry needs to remain in the cache.

VaryByHeader: Gets or sets a well delimited set of HTTP header names that are used to change cache entries.

Location: Gets or sets a value that determines the location of the cached item, including any, Clint, downstream, None, server, and ServerAndClient. The default value is any.

VaryByControl: Gets or sets a cluster of delimited control identifiers that are contained within the current page or user control to change the current cache entry.

Nostore: Gets or sets a value that determines whether the "Http cache-control:no-store" directive is set.

VaryByCustom: Gets the list of custom strings that the output cache uses to change cache entries.

Enabled: Gets or sets a value that indicates whether output caching is enabled for the current content.

VaryByParam: Gets a list of query strings or form post parameters.
