do you really have that many visitors that you need to run your site on two different servers? i'm not sure if this is what you want really but here it is. <?php$rand = mt_rand(1,2);if($rand == "1") { //redirect to other server}else{ //stay at this server}?>you will have to fill in the if statements with how you want to redirect the user.

If there on the same network, it's not going to be that easy using php...The server should have some software that allows you to set a load balancer and tell it what to do if it is exceeded. The best way using php would be to have 2 addresses, like example.com and www.example.com... one of them on each server.---- ---SFB, he may have too small and old server which can't take alot to begin with, but he must have alot of people still... like 100 at any given time.

No kidding, people don't do load balancing this way. What about the server taking all the requests to decide which server to send everyone to? There's still only one, and it would still get slammed. Also, it would totally screw up sessions if a user sent one request to one server and the next request to a different server where the 2 servers are basically independent.If you want to do load balancing or clustering, there is hardware to do exactly that.http://content.websitegear.com/article/loa...nce_methods.htmNote that writing your own script in PHP is not one of the methods

You can use % (mod operator) to see if a number is odd or even.if ($no % 2 != 0)echo "odd";elseecho "even";Probably you can also use (but it's a little harder to understand):if ($no & 1)echo "odd";elseecho "even";

Detail what? Are you detailing your car? Because this is the wrong forum for that. But if you are, I would like you to detail my car as well, because it rained recently.
