Coldfusion per application mapping randomly fails

Question

In my application.cfc file I have the following code:

this.mappings["/includes"] = "#expandPath('../../priv/inc/')#";

and then on a page I have the following CF include set up:

<cfinclude template="/includes/imageOptimise-thumbnail.cfm">

For the majority of the time when the page is submitted the imageOptimise-thumbnail page runs without any issue but occasionally it will error saying that it can't find the imageOptimise-thumbnail.cfm. If I resubmit the page, chances are it will work but the question is, why is it sometimes not being able to find the page?

I had a look in the CF Admin and I can't see anything in the logs saying that there was an error but it is clearly showing a Coldfusion 'template not found' error message when it fails.

Anyone got any ideas?

I think your issues stem from the fact that the path used for the mapping is relative.

According to advice in ColdFusion Mappings and Relative Paths,

the moral of the story is to NEVER use expandPath() to create a mapping that’s relative to the webroot.

Try to make the webroot static as the blog suggests

<cfset this.mappings["/myapplication"] =getDirectoryFromPath(getCurrentTemplatePath())

and navigate to /priv/inc/ from the webroot
