How can I troubleshoot output caching issues in MVC?

I'm having trouble with output caching in my MVC application. It seems like the cached data isn't updating.

Output caching can sometimes cause issues if the cache isn't invalidated properly. Have you checked the cache duration settings?

Yes, I set the duration to 60 seconds, but the data still seems stale after that.

In that case, you might want to look into cache dependencies or consider using the OutputCache attribute with varying parameters.

What are cache dependencies? How do they work?

Cache dependencies allow you to invalidate the cache based on changes to specific data. For example, if a database record changes, the cache can be cleared automatically.
