Prevent google chrome cache html page

Question

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.

Solution 1

Set the correct expiry headers in the HTTP response from your server. They override anything you've put in meta tags.

Solution 2

This works in Chrome:

<meta http-equiv="cache-control" content="max-age=0" />
<meta http-equiv="cache-control" content="no-store" />
<meta http-equiv="expires" content="-1" />
<meta http-equiv="expires" content="Tue, 01 Jan 1980 1:00:00 GMT" />
<meta http-equiv="pragma" content="no-cache" />

I found this in a Chromium bug. https://bugs.chromium.org/p/chromium/issues/detail?id=28035

I'm noob at server managerment. I put this on .htaccess file : <filesMatch "\.(html|htm|js|css)$"> FileETag None <ifModule mod_headers.c> Header unset ETag Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate" Header set Pragma "no-cache" Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT" </ifModule> </filesMatch> Is good ?

@Tran Is it working? You'll probably need to clear you browser cache.

this did not work for me, chrome still gets if from cache.

Just to let you know, this unfortunately does not work. Had these exact settings and a new release caused hell across the country!
