<?php
   
session_start();
?>

<form action="session2.php?" method="Post">
        <table align="center" border=0 cellspacing=5 cellpadding=0 width="100%">


        <table>
          <tr>
          <th align="left">Address :</th>
              <td><input type="text" size = "55" name="address1"/></td>
              <td><input type="text" size = "55" name="address2"/></td>
          </tr>
        </table>
        <center><input type="submit" name="submit" value="Submit"><input type="reset" Value="Reset"/></center>
        </form>


page2:
<?php
// page1.php

session_start();

$_session['address1']=$_POST['address1'];
$_session['address2']=$_POST['address2'];

echo "1:".$_session['address1'];
echo "
2:".$_session['address2'];

session_destroy();

-------------------------------------------

Try This

[quote]<?php
 
session_start();

[color=red]header("Cache-control: private");[/color]
?>

<form action="session2.php?" method="Post">
        <table align="center" border=0 cellspacing=5 cellpadding=0 width="100%">


        <table>
          <tr>
          <th align="left">Address :</th>
              <td><input type="text" size = "55" name="address1"/></td>
              <td><input type="text" size = "55" name="address2"/></td>
          </tr>
        </table>
        <center><input type="submit" name="submit" value="Submit"><input type="reset" Value="Reset"/></center>
        </form>


page2:
