<cfif not isdefined("application.utils") or isdefined("url.reinit")>
  <cflock scope="Application" type="Exclusive" timeout=30>
    <cfset application.utils = createObject("component","path.to.utils")>
  </cflock>
</cfif>


Is the cflock necessary?

		Components stored in the application-scope are created once per application.

Isn't the application scope also stored once for each visitor? I'll admit I'm somewhat green in this area. Any explanation is appreciated!

		Better to load something like this into the Application scope. Why have a CFC stored once in memory for each visitor when you could store it once in the Application scope and reference it (with new values) any time you needed it?

		Hi Eva, sorry I didn't see your question until today when I was notified of Lou's comment.

To load the cfc into a variable, you can set it up when you start a session. Like so:
<pre><cfset session.utils = createObject("component","path.to.utils")></pre>
And make sure the file name is 'utils.cfc' (or update your createObject accordingly).

What I meant by "The value is preloaded from a CFQuery called ‘read’" is that there would be a query that gets the textarea's value from a database. In the examples above, the CFQuery's name is 'read' and the fieldname is 'metadesc'.
