What is server-side caching and how does it work?

Server-side caching is a technique where data is stored on the server to reduce load times and improve performance. It works by saving the output of expensive database queries or computations, so that subsequent requests can retrieve the cached data instead of recalculating it.

What are the benefits of using server-side caching?

The benefits include faster response times, reduced server load, improved scalability, and a better user experience. It can significantly decrease the time it takes to serve content to users.

Are there different types of server-side caching?

Yes, there are several types, including object caching, page caching, and opcode caching. Each serves different purposes and can be used in various scenarios.

How do I implement server-side caching in my application?

Implementation depends on your tech stack, but generally, you can use caching libraries or frameworks specific to your programming language, like Redis or Memcached for object caching.

Can server-side caching affect data consistency?

Yes, it can. If the cached data is not updated properly, it may lead to stale data being served. It's important to implement cache invalidation strategies.
