<h2>AJAX - The Server-Side ASP Script</h2>
<p>Now we are going to create the script that displays the current 
server time.</p>
<p>The responseText property (explained in the previous chapter) will store the 
data returned from the server. Here we want to send back the 
current time. The code in &quot;time.asp&quot; looks like this:</p>

<table class="ex" width="100%" border="1" id="table13"><tr><td>
<pre>&lt;%
response.expires=-1
response.write(time)
%&gt;</pre>
</td></tr></table>
<p><b>Note:</b> The Expires property sets how long (in minutes) a page will be 
cached on a browser before it expires. If a user returns to the same page before 
it expires, the cached version is displayed. Response.Expires=-1 indicates that 
the page will never be cached.</p>
<hr />

<h2>Run Your AJAX Application</h2>
<p>Try the AJAX application by typing some text into the Name text 
box below, then click inside the Time text box:</p>
<form name="myForm">
Name: <input type="text"
onkeyup="ajaxFunction();" name="username" />
Time: <input type="text" name="time" />
</form>
<p>The Time text box gets the server's time from &quot;time.asp&quot; 
file without reloading the page!</p>
