redirect

I have three websites hosted (example1.com, example2.com, example3.com) on a server. There is a page (test.php) on example1.com with just code below inside it:

<?php
  header('Location:http://example2.com/a.php');
?>

When I browse test.php it goes to http://example1.com/a.php . it doesn't understand it is another domain url, it tried to find the page on itself.

but when I put http://google.com instead of example2.com/a.php it works correct. I really get confused.

What is the problem ? Should I set some configuration on the server?

( I am administrator of the hosting server ). Ps. The server is behind a pound server.

Here's the Firebug Net output for example1.com/test.php
