ERR_CACHE_MISS: check before resubmitting the form

Chrome says this page needs information previously entered to be submitted again. If the form placed an order or made another change, check the result before approving a repeat submission.

The short version

  1. 01Record whether the page was reached by a form submission, refresh or Back navigation.
  2. 02Preserve any form text that is still visible before leaving the page.
  3. 03Check the account, confirmation or transaction history for an already completed action.
  4. 04Reopen the original form if you need a fresh attempt instead of repeatedly refreshing the result page.
  5. 05Resubmit a form that changes data only after confirming a repeat is appropriate.
  6. 06As the owner, use a GET confirmation page after successful POST handling where the workflow permits it.

Raw message

ERR_CACHE_MISS

Likely causes

  • Chrome needs previously entered information to load the page again.
  • A page reached through a form submission requires a deliberate repeat rather than an automatic replay.

Check the form result before sending it again

Google defines ERR_CACHE_MISS as a page needing information previously entered to be resubmitted. Our first check is what that submission did: a search can be repeated differently from an order or an account change. Keep visible input and check for a confirmation or completed action before agreeing to resend.

Use a fresh form when another attempt is needed

HTTP's retry rules do not permit automatic repetition of a non-idempotent operation unless the client knows it is safe or the original did not apply. Our recommendation is to reopen the original form and deliberately decide whether to submit again. A missing result page alone does not establish that the action failed.

Owners: redirect a successful POST to a confirmation GET

MDN documents 303 See Other as a redirect commonly used after POST or PUT, with the destination retrieved using GET. Where appropriate, that gives a successful form a separate confirmation page. Our recommendation is to review result-page handling rather than ask visitors to repeatedly resend the same operation.

Sources and review notes

Checked on . Chrome supplies the error meaning. HTTP retry semantics and MDN's 303 explanation inform the form-handling guidance. Preserving input, checking completed actions and reopening a form are editorial recommendations. This is not a diagnosis that every cache miss requires clearing all browser data. Glitchary is independent of Google.
