Clear HTMLDialog Cache


I’m the developer of a plugin for sketchup that access an external website that is hosted in our servers with HTMLDialog/WebDialog. The point is that many times we need to clean manually the webcache folder of sketchup (or Clear the cache in IE for Webdialog) to make it update the dialog webpage what is totally non user friendly for our users. There’s a way to clear the cache used in HTMLDialog and WebDialog by code?
