so in case you are not using user-id and you have /24 subnets you can use the following response page:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Web Page Blocked</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">
<meta name="viewport" content="initial-scale=1.0">
<style>
#content {
border:3px solid#aaa;
background-color:#fff;
margin:1.5em;
padding:1.5em;
font-family:Tahoma,Helvetica,Arial,sans-serif;
font-size:1em;
}
h1 {
font-size:1.3em;
font-weight:bold;
color:#196390;
}
b {
font-weight:normal;
color:#196390;
}
</style>
<script type="text/javascript">
function onload()
{
var ip = "<user/>";
var octets = ip.split(".");
var subnet = octets[0] + "." + octets[1] + "." + octets[2];
var title = document.getElementById("title");
var infotext = document.getElementById("infotext");
switch (subnet) {
case "10.0.0":
title.innerHTML = "Title 1";
infotext.innerHTML = "Infotext 1";
break;
case "10.0.1":
title.innerHTML = "Title 2";
infotext.innerHTML = "Infotext 2";
break;
case "10.0.2":
title.innerHTML = "Title 3";
infotext.innerHTML = "Infotext 3";
break;
}
}
</script>
</head>
<body bgcolor="#e7e8e9" onload="onload()">
<div id="content">
<h1 id="title">Web Page Blocked</h1>
<p id="infotext">Access to the web page you were trying to visit has been blocked in accordance with company policy. Please contact your system administrator if you believe this is in error.</p>
<p><b>User/IP:</b> <user/> </p>
<p><b>URL:</b> <url/> </p>
<p><b>Category:</b> <category/> </p>
</div>
</body>
</html>
The only thing you need to change is the statements in the switch statement according to your subnets and the title and text you want to display to the user.
