Some versions of IE have trouble obeying no cache meta tags. Here's
the code I use to prevent caching with CF 5 -- probably snagged it
from this list.
---------
<!--- Client side cache prevention --->
<meta http-equiv="Expires" content="0">
<!--- Setup our expire times for Netscape and Internet Explorer --->
<cfoutput>
<!--- Internet Explorer Date Format: (eg, Fri, 30 Oct 1998
14:19:41 GMT) --->
<cfset
MSIEtimestamp='#dateformat(now(),"DDD")#,#dateformat(now(),"DD")#
#dateformat(now(),"Mmm")# #timeformat(now(),"HH:MM:SS")#'>
<!--- Netscape Date Formate: Netscape (eg, Wednesday, Apr 26
2000 17:45:25 PM) --->
<cfset
NETSCAPEtimestamp='#dateformat(now(),"DDDD")#,#dateformat(now(),"MMM")
#
#dateformat(now(),"dd")# #dateformat(now(),"YYY")#
#timeformat(now(),"HH:MM:SS tt")#'>
</cfoutput>
<!--- Tell HTTP Header to force expire of page - nocache --->
<cfif HTTP_USER_AGENT contains "MSIE">
<cfheader name="Expires"
value="<cfoutput>#MSIEtimestamp#</cfoutput>">
<cfheader name="Pragma" value="no-cache">
<cfheader name="cache-control" value="no-cache, no-store,
must-revalidate">
<cfelse>
<cfheader name="Expires"
value="<cfoutput>#NETSCAPEtimestamp#</cfoutput>">
<cfheader name="Pragma" value="no-cache">
<cfheader name="cache-control" value="no-cache, no-store,
must-revalidate">
</cfif>
