Hello, and welcome to the MyBookmarks Apache::ASP demo application.
To begin your bookmark experience, please login now:

<center>
<% if($error) { %>
	<p><b><font color=red size=-1>* <%=$error%></font></b>
<% } %>
<form src=<%=$Basename%> method=POST>
<input type=text name=user value="<%=$Server->HTMLEncode($user)%>">
<input type=submit value=Login>
</form>
</center>

This demo makes use of the Apache::ASP objects, especially
<tt>$Session</tt> and <tt>$Response</tt>, modularizes html 
via SSI file includes, and uses the <tt>Script_OnStart</tt>
and  <tt>Script_OnEnd</tt> event hooks to 
simplify common tasks done for each script in this web
application.
