How to access localhost over LAN ip in php?

Hi guys i have three simple php pages login.php,process.php and login_success.php.The problem is that login.php and process.php is present in my localhost:8080 but login_success.php is present at 192.168.1.36:8080 but on same lan.I am perfectly accessing my login.php but on clicking button it is not displaying login_success.php.I am using XAMPP server and it is installed in both the systems.The other thing is that i am accessing logout_success.php through url directly for e.g. http://192.168.1.36/xampp/logout_success.php. My code is very simple All my code is as follows:

<form action="process.php" method="POST">
    username:<input type="text" name="username"/>
            <br/>
    password:<input type="password" name="pass"/>
            <br/>
             <input type="submit" value="Login!"/>
</form>

Process.php:

<?php
  $username = $_POST['username'];
  $password = $_POST['pass'];

   if($username == 'test' AND $password == 'test')
    {
      header('Location : http://192.168.1.36/xampp/logout_success.php');
    }
   else
    {
      echo "You have not logged in,username or password is incorrect!";
    }
?>

Login_success.php:

<html>
  <body>
    Logout Success<br>
    Thanks for using the Captive Portal...
  </body>
</html>

Can anyone tell me how to access login_success.phppage.Any help would be greatly appreciable.

Solution

Got a white space within the header call.

Change

  header('Location : http://192.168.1.36/xampp/logout_success.php');

  header('Location: http://192.168.1.36/xampp/logout_success.php');

Entire Code:

index.php

<form action="process.php" method="POST">
    username:<input type="text" name="username"/>
            <br/>
    password:<input type="password" name="pass"/>
            <br/>
             <input type="submit" value="Login!"/>
</form>

process.php

<?php
  $username = $_POST['username'];
  $password = $_POST['pass'];

   if($username == 'test' AND $password == 'test')
    {
      header('Location: login_success.php');
    }
   else
    {
      echo "You have not logged in,username or password is incorrect!";
    }
?>

login_success.php

<html>
<head></head>
  <body>
    Logout Success<br>
    Thanks for using the Captive Portal...
  </body>
</html>

Make sure the file names are right (lowercase). I have tried it on my test server and it seems to work. (http://jagmit.co.uk/test/php_login/)

Also, i just would like to remind you that this is a bad example of how NOT to implement a login security system.
