What are some effective strategies for dynamic content caching?

Dynamic content caching involves storing frequently accessed data to improve performance. Some effective strategies include using cache expiration policies, implementing cache invalidation techniques, and leveraging content delivery networks (CDNs) to cache content closer to users.

Can you explain cache expiration policies?

Cache expiration policies determine how long cached content remains valid. Common strategies include time-based expiration, where content is refreshed after a set period, and event-based expiration, which updates the cache when specific changes occur.

What is cache invalidation?

Cache invalidation is the process of removing or updating cached content when the underlying data changes. This ensures users receive the most current information and prevents stale data from being served.

How do CDNs help with caching?

CDNs cache content at various locations around the world, reducing latency and improving load times for users by serving cached content from the nearest server.
