Use PHP to disable browser back-off: 1. Add [] tag to the header and securely connect [pragma: no-cache] to prevent the browser from caching the page; 2. Use program control , remove [no-store] in []
##Use php to disable the browser Ways to fall back:
The best solution is to use a mix of client-side scripts and server-side scripts.
The easiest way is to add the tag in the header
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache,no-store, must-revalidate"> <META HTTP-EQUIV="pragma" CONTENT="no-cache"> <META HTTP-EQUIV="expires" CONTENT="0">
"pragma: no-cache" only prevents the browser from caching the page when using a secure connection. For unprotected pages, "pragma: no-cache" is treated the same as "expires: -1", in which case the browser still caches the page but marks the page as expired immediately.
In addition, you can also use program control
<?php header("Cache-control:no-cache,no-store,must-revalidate"); header("Pragma:no-cache"); header("Expires:0"); ?>
or
header(“Cache-control:no-cache,no-store,must-revalidate”); is missing
