How can I get post paramers from page redirection using ajax?

[phpuser123]

I have a page client.php that submits a form and goes to server.php..
server.php adds some post requests and redirects the page to client.php..
Is it possible to use ajax here to access the post parameters from server.php ?

I am a new bie in ajax and php.
Server redirection = post request to client.php
How can I use ajax here to prevent the page loading problem..

client.php

    <form name ="Play" method="post" action="server.php"><input name="fname" valie="fname" /><input name="sbmt" value="Submit"></form>
    <?php
       if (isset($_POST['rname'])){
         echo $_POST['rname'];
        }
     ?>
