HTTP caching
HTTP caching controls when clients and intermediaries can reuse a response.
Use this when A response is unexpectedly stale or reused for the wrong user.
without the term
“After deploying, some users still get the old JavaScript, and I'm worried a logged-in page might get cached and shown to others. Can you set the cache headers properly?”
with the term · How do you ask a model for HTTP caching?
Set deliberate HTTP caching for these responses. Verify public-asset reuse, private-data isolation, and revalidation after changes.
What is HTTP caching?
Cache-Control and related headers tell browsers and shared caches whether they may store a response, for how long, and how to check it is still valid. Private data must never land in a shared cache.
Why does HTTP caching matter when vibe coding?
One cache header copied everywhere can be incorrect for both assets and private data.
How do you do HTTP caching?
Classify responses, define validation and variants, and test the actual browser or shared cache.
What goes wrong with HTTP caching?
Reading no-cache as a prohibition on storage; it requires validation before reuse.
