Hi Dan Thanks for that - it seems to be working fine. So this will now cache the RSS feed to the application scope for 20 mins, so the CFHTTP tag does not need to go out to the Internet within the 20 minute timeframe as the data from the feed is cached?

Change the code to something like: <cfif not structKeyExists(Application, "TimeStamp") or (dateDiff("n", Application.TimeStamp, now()) gt 20)> <cfset Application.TimeStamp = now() /> <cfhttp url="http://feeds.bbc.co.uk/weather/feeds/rss/5day/id/3314.xml"; method="GET" resolveurl="No"></cfhttp> <cfset Application.weather_xml = xmlParse(cfhttp.FileContent) /> </cfif> There's no need to convert your Application.TimeStamp variable to any specific formatting--you can just set it to now(). -Dan ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295476 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
