The *client* can do that. Whether it has that kind of functionality is another question. Whether it's enabled by default or has to be enabled by the user configuring the client is another question. Whether your server knows what client is being used, and whether that client supports the function, and what to send it to cause this to happen...

If you have control over the client, then that's trivial. But since you're asking, my guess is you don't?
