What is the difference between output cache and data cache in ASP.NET?

What is the difference between output cache and data cache in ASP.NET?

The output cache stores the rendered HTML of a page, while the data cache stores data objects. Output cache improves response time for static content, whereas data cache is used for dynamic data retrieval.

Can you give me an example of when to use each?

Sure! Use output cache for pages that don't change often, like a product page. Use data cache for frequently accessed data, like user profiles.

Are there any performance implications for using one over the other?

Yes, using output cache can significantly reduce server load and improve response times for static content. Data cache can speed up data retrieval but may require more memory.

How do I implement both in my ASP.NET application?

You can implement output caching using the OutputCache directive in your ASPX pages, and for data caching, you can use the Cache class in your code to store and retrieve data.
