The server can handle this with <page>net.Receive</page>. Remember that **any** client has the potential to send any net message at any time. **Don't trust the client-side!** On your server-side <page>net.Receive</page>, make sure to verify the message sender's permissions whenever you can and prevent expensive functions from being run too often. </output> </example>
