How to detect network caching/filtering simply?

I work for a company that develops, hosts, and licenses a web-based career guidance app that breaks when it is subjected to caching/filtering. How can we detect if this is happening?

The application depends on providing instant feedback to individual students, who each have a unique account. We've found that any caching on the school network results in actions not being saved correctly, thus student progress is not being recorded. One of the setup tasks for any school or district who license the application is to whitelist all of our hosts, but as is the way of such things, some IT departments do not or cannot completely exempt our traffic.
This is not related to browser caching; that can be handled by the application and is not an issue. We need to be able to detect when traffic between the student and our servers is being cached via a proxy or filter.
Is there a simple test that we can ask teachers to perform that would let us know if caching is still present? If such a test involves setting something up on our servers, we would be willing to do so; a reliable diagnosis would save a lot of time, headaches, and user frustration.
