About Cache-Control Guru

Your go-to resource for HTTP caching headers

What is Cache-Control?

The Cache-Control HTTP header field is used to specify browser caching policies in both client requests and server responses. Policies include how a resource is cached, where it's cached, and its maximum age before expiring.

Why is caching important?

Proper caching strategies can significantly improve web performance by:

  • Reducing network traffic and bandwidth costs
  • Lowering server load
  • Decreasing page load times
  • Improving user experience

  • Explain Mode: Paste in an existing cache-control header to understand what each directive means
  • Generate Mode: Use a form-based interface to build the perfect cache-control header for your needs
