A Simple onMissingTemplate Example

Posted by Paul Marcotte | Tags: ColdFusion

For the migration to Mango Blog, I wanted to preserve my previous RSS feed location (/rss.cfm). The new location is feeds/rss.cfm. With the availability of onMissingTemplate event handler for ColdFusion 8, making sure my RSS didn't break was a snap. Here's the snippet of code I added to Application.cfc.

<cffunction name="onMissingTemplate" returntype="void">
   <cfargument name="thePage" type="string" required="true">
   <cfif arguments.thePage is "/blog/rss.cfm">
      <cflocation url="/blog/feeds/rss.cfm" addtoken="false" />
   </cfif>
</cffunction>

Not the most elegant solution I've ever developed, but it keeps the RSS feed alive until I decide how I want to manage it the future...

Is the change of URL permanent? In which case, you should do a 301 redirect by adding statuscode="301" (In CF8) or

<cfheader statuscode="301" statustext="Moved Permanently">
<cfheader name="Location" value="/blog/feeds/rss.cfm">

in CF7

Fabregas free running, running, and he used his tactical awareness of a great help for us. Coach Guardiola said. Among the melon handsome imagination, Washington Redskins Jerseys Albert Haynesworth Jersey Brian Orakpo Jersey Chris Cooley Jersey Chris Horton Jersey Fabregas will play more events on the pitch middle midfielder role. During the Arsenal, Fabregas repeated muscle injuries. But in fact, Washington Redskins Jersey Clinton Portis Jersey Darrell Green Jersey DeAngelo Hall Jersey Devin Thomas Jersey he and Lionel Messi, as has a very strong muscles, so to adapt to the Barcelona game no problem. This makes Guardiola was very satisfied. His goal should be to go beyond the resume Harvey.
