What is the difference between cache and no-cache in web development?

What is the difference between cache and no-cache in web development?

In web development, 'cache' allows browsers to store copies of files to speed up loading times, while 'no-cache' forces the browser to revalidate the files with the server before using the cached version.

When should I use no-cache instead of cache?

You should use 'no-cache' when you want to ensure that users always receive the most up-to-date content, such as in dynamic applications or when content changes frequently.

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

Sure! You can use 'cache' for static assets like images, CSS, and JavaScript files that don't change often, improving load times for returning visitors.

What are the performance implications of using cache?

Using cache can significantly improve performance by reducing load times and server requests, but it can also lead to outdated content if not managed properly.
