What is the difference between Cache-Control and Expires headers?
An example of an AI chatbot conversation about Cache-Control vs Expires headers in HTTP.
What is the difference between Cache-Control and Expires headers?
Cache-Control is a HTTP header that specifies directives for caching mechanisms in both requests and responses. Expires, on the other hand, is an older HTTP header that indicates a specific date and time after which the response is considered stale.
Which one should I use for better control over caching?
It's generally recommended to use Cache-Control because it provides more granular control over caching behavior compared to Expires.
Can you give me an example of how to use Cache-Control?
Sure! You can use Cache-Control like this: Cache-Control: no-cache, no-store, must-revalidate to prevent caching.
What about Expires? How would I use that?
You can set an Expires header like this: Expires: Wed, 21 Oct 2025 07:28:00 GMT to specify when the content should be considered stale.
