<h1>How to redirect domains or subdomains?</h1> 
 
By default, all domain names and subdomain names are sent to the default page located inside the webroot folder. Due to restrictions with Brinkster's shared hosting plans, multiple domain names and sub domain names need to be redirected manually through code if you wish for them to show different content. 
 
 
Resolution 
Use one of the following code samples in your default page to redirect visitors to different locations depending on the domain they type in. 
 
The following is an example of ASP code. You will need to save the page as default.asp or index.asp. 
This code sample will *include* content from another page, leaving the URL in the URL bar of the web browser alone.

<table style="font-size: 8pt; color: black; font-family: courier" cellspacing="0" cellpadding="1" width="100%" bgcolor="#eeeeee" border="0">
 <tbody>
 <tr>
 <td>
 <pre style="text-align: justify">
<%@Language=VBScript%>
 <%
 SiteNameURL = Request.ServerVariables("SERVER_NAME") 
 
 Select Case SiteNameURL
 Case "yourdomain.com"
 %><%
 
 Case "www.yourdomain.com"
 %><%
 
 Case "yourotherdomain.com"
 %><%
 
 Case "www.yourotherdomain.com"
 %><%
 
 Case "subdomain1.yourdomain.com"
 %><%
 
 Case "subdomain2.yourdomain.com"
 %><%
 
 Case Else 'redirecting everything other than cases selected above
 %><%
 End Select
 %>
 </pre>
 </td>
 </tr>
 </tbody>
</table>

 
 
The following is an example of ASP code. You will need to save the page as default.asp or index.asp. 
This code sample will redirect visitors to the corresponding page, changing the URL, for example http://domain.com/page1.asp.

<table style="font-size: 8pt; color: black; font-family: courier" cellspacing="0" cellpadding="1" width="100%" bgcolor="#eeeeee" border="0">
 <tbody>
 <tr>
 <td>
 <pre style="text-align: justify">
<%@Language=VBScript%>
 <%
 SiteNameURL = Request.ServerVariables("SERVER_NAME") 
 
 Select Case SiteNameURL
 Case "yourdomain.com"
 Response.Redirect "page1.asp"
 
 Case "www.yourdomain.com"
 Response.Redirect "page1.asp"
 
 Case "yourotherdomain.com"
 Response.Redirect "page2.asp"
 
 Case "www.yourotherdomain.com"
 Response.Redirect "page2.asp"
 
 Case "subdomain1.yourdomain.com"
 Response.Redirect "page3.asp"
 
 Case "subdomain2.yourdomain.com"
 Response.Redirect "page4.asp"
 
 Case Else 'redirecting everything other than cases selected above
 Response.Redirect "other.asp"
 End Select
 %>
 </pre>
 </td>
 </tr>
 </tbody>
</table>

 
 
The following is an example of PHP code. You will need to save the page as default.php or index.php. 
This code sample will redirect visitors to the corresponding page, changing the URL, for example http://domain.com/page1.php. 
All domain names entries should be lower case.

<table style="font-size: 8pt; color: black; font-family: courier" cellspacing="0" cellpadding="1" width="100%" bgcolor="#eeeeee" border="0">
 <tbody>
 <tr>
 <td>
 <pre style="text-align: justify"> <?
 $SiteNameURL = $_SERVER['HTTP_HOST'];
 
 switch (strtolower($SiteNameURL)) {
 
 case "domain.com": //MUST BE LOWER CASE
 
 header("Location: http://" . $_SERVER['HTTP_HOST'] . "/page1.php");
 break;
 
 case "www.domain.com": //MUST BE LOWER CASE
 
 header("Location: http://" . $_SERVER['HTTP_HOST'] . "/page1.php");
 break; 
 
 case "yourotherdomain.com": //MUST BE LOWER CASE
 
 header("Location: http://" . $_SERVER['HTTP_HOST'] . "/page2.php");
 break;
 
 case "www.yourotherdomain.com": //MUST BE LOWER CASE
 
 header("Location: http://" . $_SERVER['HTTP_HOST'] . "/page2.php");
 break; 
 
 case "subdomain1.domain.com": //MUST BE LOWER CASE
 
 header("Location: http://" . $_SERVER['HTTP_HOST'] . "/page3.php");
 break;
 
 case "subdomain2.domain.com": //MUST BE LOWER CASE
 
 header("Location: http://" . $_SERVER['HTTP_HOST'] . "/page4.php");
 break; 
 
 default:
 header("Location: http://" . $_SERVER['HTTP_HOST'] . "/other.php");
 
 }
 ?>
 </pre>

The following example uses JavaScript code. You will need to save the page as an HTML document, using .html or .htm as the file extension. This code sample will redirect visitors to the corresponding page, changing the URL, for example http://domain.com/page1.php.

<table style="font-size: 8pt; color: black; font-family: courier" cellspacing="0" cellpadding="1" width="100%" bgcolor="#eeeeee" border="0">
 <tbody>
 <tr>
 <td>
 <pre style="text-align: justify">
<html>
 <head>
 <title>Redirect Script with JavaScript</title>
 <script language=javascript>
 var whois=location+" "
 
 if (whois.indexOf("yourdomain.com") != -1)
 { window.location ="page1.html" }
 
 if (whois.indexOf("www.yourdomain.com") != -1)
 { window.location ="page1.html" }
 
 if (whois.indexOf("yourotherdomain.com") != -1)
 { window.location ="page2.html" }
 
 if (whois.indexOf("www.yourotherdomain.com") != -1)
 { window.location ="page2.html" }
 
 if (whois.indexOf("subdomain1.yourdomain.com") != -1)
 { window.location ="page3.html" }
 
 if (whois.indexOf("subdomain2.yourdomain.com") != -1)
 { window.location ="page4.html" }
 
 </script>
 </head>
 <body>
 </body>
 </html>
</pre>
 </td>
 </tr>
 </tbody>
</table>
