How does cache control work in different web frameworks?

Cache control is a mechanism that allows web developers to specify how and for how long browsers and other caches should store resources. Different frameworks implement cache control in various ways.

Can you give examples of how to set cache control in Express and Django?

In Express, you can set cache control headers using the res.set method. For example: res.set('Cache-Control', 'public, max-age=3600');. In Django, you can use the @cache_control decorator to set cache headers.

What are the common cache control directives I should know?

Common cache control directives include max-age, no-cache, no-store, and must-revalidate. Each directive serves a specific purpose in controlling how resources are cached.

How do these directives affect performance?

Using appropriate cache control directives can significantly improve performance by reducing load times and server requests, as cached resources can be served directly from the user's browser.
