How to to use cache in asp.net for cache?

Question

ICSM Computer · Answer

In ASP.NET (non-Core), caching is a powerful feature to improve performance by storing data temporarily. You can cache data, pages, or fragments of pages. 1. Using HttpRuntime.Cache / HttpContext.Cache (In-Memory Cache) Best for caching data like query results or processed objects. Example: Caching Data in Code 2. Cache Insert with Callback (Auto Remove Notification) 3. Page Output Caching (Full Page Cache) Caches the entire HTML output of a page. In ASPX Page: Duration="60": cache for 60 seconds.VaryByParam="none": same cache for all query parameters. 4. Fragment Caching (User Control or Partial Cache) Useful if part of your page changes often, but other parts don’t. Example in ASPX User Control: Include this user control in your page: 5. Cache with Dependencies (Auto Invalidate on File/DB Change) Cache is cleared if the XML file changes. 6. Remove from Cache Note This is in-memory per AppDomain, so if your app restarts or is scaled across servers, the cache is reset.For distributed cache (like Redis), you'd need external providers or ASP.NET Core.
