<h3>Lock Method</h3>
<p>The Lock method prevents other users from modifying the variables in the Application
object (used to ensure that only one client at a time can modify the Application
variables).</p>
<h3>Unlock Method</h3>
<p>The Unlock method enables other users to modify the variables stored in the Application object
(after it has been locked using the Lock method).</p>
<h3>Syntax</h3>

<pre>Application.Lock</pre>
<pre>Application.Unlock</pre>

<tr>
<td valign="top">
<p>The example below uses the Lock method to prevent more than one user from accessing the variable
visits at a time, and the Unlock method to unlock the locked object so that the next client can increment
the variable visits:</p>
<pre><%
Application.Lock
Application("visits")=Application("visits")+1
Application.Unlock
%></pre>
<pre>This page has been visited
