It's not so much an issue with CF and AOL as much as it's an issue with the
world and AOL.
AOL's proxy servers cache pages in an EXTREMELY agreesive manner. Any site
with dynamic content, or authentication requirements is at risk of
corruption or security breaches unless every measure possible is taken to
tell AOL's proxies NOT to cache the page.
The following headers should be sent with every request:
<CFSET gmt = gettimezoneinfo()>
<CFSET gmt = gmt.utcHourOffset>
<CFIF gmt EQ 0>
<CFSET gmt = "">
<CFELSEIF gmt GT 0>
<CFSET gmt = "+" & gmt >
</CFIF>
<CFHEADER NAME="Pragma" VALUE="no-cache">
<CFHEADER NAME="Cache-Control" VALUE="no-cache, must-revalidate">
<CFHEADER NAME="Last-Modified" VALUE="#dateformat(now(), 'ddd, dd mmm
yyyy')# timeformat(now(), 'HH:mm:ss') GMT#gmt#">
<CFHEADER NAME="Expires" VALUE="Mon, 26 Jul 1997 05:00:00 GMT">
So far, this has worked to prevent problems caused by AOL's proxies on my
sites. Be warned, however, that AOL's evil engineers occasionally tweak the
servers to defeat such measures. (It's cheaper for them to cache everything
than it is to buy proper bandwidth)
