Detect Screen Width Cold Fusion 9

Question

We are trying to execute a cfinclude determined by screen width on our responsive website. This if for determining the number of ads that will appear on the page (we want to show a fixed number on screens of 700px or less). We are using Cold Fusion 9 so we can't utilize CF 11's detectDevice function. We realize we can't just use media queries to show or hide the appropriate cfinclude because this will not prevent CF from loading unnecessary ads in the background, it will just hide them and our page speed will be affected. Is Javascript the only way to do this? If so, can someone provide an example without Jquery?

I would suggest either learning javascript or better yet, learn javascript and incorporate a responsive framework like bootstrap 3. Trust me, maintaining width specific include modules on the server will rapidly become a nightmare for you or whoever inherits the project.

There is a way to do it in ColdFusion 2018.Be aware that the Adobe documentation has a typo "cfclient.width" leaving the "properties" out.
