Example to expire and have no-caching of Web pages in Internet Explorer:
https://support.microsoft.com/en-us/help/234067/how-to-prevent-caching-in-internet-explorer
<HTML> <HEAD> <META HTTP-EQUIV="REFRESH" CONTENT="5"> <TITLE> Pragma No-cache < /TITLE> </HEAD> <BODY> LANSA HTML code etc... belongs here </BODY> <HEAD> <META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE" /> <META HTTP-EQUIV="EXPIRES" CONTENT="-1" /> </HEAD> </HTML>
For the tag "< meta http-equiv="expires" content="-1" /> " -1 means do not cache and expire straight away.
Therefore, when the user click the Back button, they will get the warning: Page has Expired - Please Refresh or resubmit information etc. in internet explorer.
Note: These meta tags need to be within the HEAD section. This is very important.
