Re: Using CFDirectory on every page

[Pete Ruckelshaus]

Why use CFDIRECTORY when you can use try/catch blocks?  Here's how I
approached the "is the include there" problem in one of my apps:


<cftry>
  <img src="#request.app.path#images/spacers/trans.gif" width="12"
height="4" /><img src="#request.app.path#images/spacers/trans.gif"
width="146" height="4" /><br><span class="navHeader">News &amp;
Events</span>
  <cfinclude template="/generated/related_links.txt"><br>
  <cfcatch type="MissingInclude">
   <!--- If the include file is missing, try to write it again... --->
   <cftry>
    <cfinclude template="/_admin_tools/related_links_to_text.cfm">
    <!--- Give the include file time to be written...in this case, 2
seconds. --->
    <cfset lockname = CreateUUID()>
     <cflock name="#lockname#" type="readonly" timeout="0">
      <cftry>
       <cflock name="#lockname#" type="exclusive" timeout="2"></cflock>
      <cfcatch type="lock"></cfcatch>
      </cftry>
     </cflock>
    <!--- And then, try the include again... --->
  <img src="#request.app.path#images/spacers/trans.gif" width="12"
height="4" /><img src="#request.app.path#images/spacers/trans.gif"
width="146" height="4" /><br><span class="navHeader">News &amp;
Events</span>
    <cfinclude template="/generated/related_links.txt"><br>
    <!--- If it's still missing, just do nothing --->
    <cfcatch type="missinginclude">Missing Include Error</cfcatch>
   </cftry>
  </cfcatch>
  <cfcatch type="Any">Unknown error</cfcatch>
 </cftry>


Works like a charm, no more missing include errors.
