I have a MySql Master server replicating to three Slaves.

A legacy website is performing load-balanced Reads from the Slaves.

Is there a method of identifying from the website which of the Slaves is serving a Read request?

I'd prefer a function that I can use to return a server name or ip address as part of the SELECT, but any reasonable method will do.

Thank you in advance.
