Remove querystring value on page refresh
<p>I am redirecting to a different page with Querystring, say </p>

<pre><code>header('location:abc.php?var=1');
</code></pre>

<p>I am able to display a message on the redirected page with the help of querystring value by using the following code, say</p>

<pre><code>if (isset ($_GET['var']))
{

    if ($_GET['var']==1) 
    {
        echo 'Done';
    }
}
</code></pre>

<p>But my problem is that the message keeps on displaying even on refreshing the page. Thus I want that the message should get removed on page refresh i.e. the value or the querystring should not exist in the url on refresh.</p>

<p>Thanks in advance.</p>
