For a PC that is set up as a kiosk always running a web browser, are there settings available in the major web browsers to delete the temporary internet files periodically? I know Firefox has settings to clear them upon closing the browser but this browser would always be up and running.
There's an article here that explains how to force major browsers to start in private mode.

You could write a program to periodically delete temporary files when a browser isnt running.
