Cache-Control builder

Build a Cache-Control response header with explicit storage and revalidation behavior.

Privacy details

Cache-Control builder processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Your result

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

Using Cache-Control builder

Cache-Control builder keeps mutually exclusive storage choices separate. Only cacheable modes include a lifetime; the result is a response header you can review before configuring your application.

A worked example

Private caching for 300 seconds with revalidation produces private, max-age=300, must-revalidate.

Before you use the result

no-cache permits storage but requires validation; no-store requests no storage. Public caching can expose personalized content if used incorrectly. This builds text only and does not change your server.
