Using wp-super-cache and amazon cloudfront - can I serve a file directly (no cdn)? [closed]

Question

I'm using the wp super cache plugin with cdn support turned on (aws cloudfront). I'm also using wp tables reloaded. The latter plugin includes a text file via ajax, and that file is being served by the cdn. The plugin doesn't do any sort of jsonp maneuvers, so the file hits access-control-allow-origin issues.

Before I go and mess with the plugin to pull the file correctly, does anyone know how I can restrict the cdn from storing this file, and just serve it up directly?
