When running an experiment through Pavlovia, I want to be sure to always serve the latest version of the experiment. Thus, I suggest that the Pavlovia servers are modified to return the following HTTP-Header for the delivery of all resources associated with running experiments (i.e., when being called through https://run.pavlovia.org/):
Cache-Control: no-cache, no-store, no-transform, must-revalidate
This will certainly increase the required bandwith a bit, but in my opinion this is more than worth it.
All the best,
Frank.
