How do I clear the cache in MVC?

To clear the cache in an MVC application, you can use the following methods: 1. Clear the output cache using OutputCache attribute. 2. Use HttpContext.Current.Cache.Remove(key) to remove specific items. 3. Clear the entire cache using HttpRuntime.Cache.RemoveAll().

Can you show me an example of using the OutputCache attribute?

Sure! You can use the OutputCache attribute like this: [OutputCache(Duration = 0, VaryByParam = "None")] on your action method to disable caching.

What if I want to clear the cache programmatically?

You can clear the cache programmatically by calling HttpContext.Current.Cache.Remove("yourCacheKey") for specific items or implement a custom method to clear all items.

Is there a way to set cache expiration?

Yes, you can set cache expiration by specifying the Duration parameter in the OutputCache attribute, which defines how long the cache should be valid.
