Hi Paul
Thanks I have tried the following where it should cache the feed in the
application.cfm page every 20 minutes but I am getting the error
Error Occurred While Processing Request
Element TIMESTAMP is undefined in APPLICATION.
Any ideas on where I am going wrong ?
---
In my application.cfm
<CFIF (APPLICATION.TimeStamp EQ "") OR (DateDiff("n",
APPLICATION.TimeStamp, TimeFormat(NOW(), "hh:mm:s")) GT 20)>
<CFSET APPLICATION.TimeStamp = CreateTime(TimeFormat(NOW(), "hh"),
TimeFormat(NOW(), "mm"), TimeFormat(NOW(), "s"))>
<CFSET APPLICATION.weather_xml =XMLParse(cfhttp.FileContent)>
<cfhttp
url="http://feeds.bbc.co.uk/weather/feeds/rss/5day/world/0008.xml";
method="GET" resolveurl="No"></cfhttp>
</CFIF>
In my display page I have the following code
<cfoutput>
<img src="#application.weather_xml.rss.channel.image.url.xmlText#"
alt="#application.weather_xml.rss.channel.item.DESCRIPTION.xmlText#">
<cfloop index="x" from="1"
to="#ArrayLen(application.weather_xml.rss.channel.item)#">
<br>
#replace(application.weather_xml.rss.channel.item[x].title.xmlText, ',',
'<br>', 'ALL')#
<br>
</cfloop>
</cfoutput>

We do this all the time, here are a couple of possibilities...
Save the RSS feed to the DB or the application scope or somewhere
reasonably persistent with a date of last retrieval associated with it.
Then when x hours have elapsed get the data again. For the most part,
you'll be using the DB or application scope to access the RSS feed...
