I have a page with another html page in iframe. In this iframe, i put this header tag
<META http-equiv="Pragma" content="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
<meta http-equiv="cache-control" content="no-cache" />
But chrome still cache it, when iframe content changed, hit f5 button but chrome still load cached version, not new version.
Please tell me how to pevent google chrome cache this iframe.
Set the correct expiry headers in the HTTP response from your server. They override anything you’ve put in
metatags.
