respond(AjaxRequestTarget target)As an illustration, you could implement a behavior that checks for WebGL support using JavaScript, transmit the result back to the Page through the Behavior, and utilize the value to replace a placeholder or fallback Panel with an enhanced version featuring WebGL capabilities.

If you're looking for a more efficient way to handle user data collection, using a custom resource could be the solution for you.

The custom resource provides a centralized location for additional data processing, allowing you to display the final result once the ajax request is complete.
