@ Mist

I will try to give you a short description how it works.
Lets see it with an example url like http://membername.boardname.com

Because you have set a catchAll-Subdomain for your topLevel-domain (*.boardname.com) all requests are going to your main html-directory.

The result of the .htaccess entry "DirectoryIndex vbsubdomain.php index.php index.html" is that the server
was first processing the file vbsubdomain.php.

In vbsubdomain.php the there are routines who
1.) get the host name (http://membername.boardname.com)
2.) get the "www." away if present
3.) delete everthing after the first slash "/" if present
4.) delete the ".boardname.com"
result of this is that we now have the pur "membername"

5.) after that it checks if "membername" is in the usersubdomain-table
if it isn?t --> auto proceed to your main hp-file like "index.php, index.htm, ..."
6.) if in table get subdomain variables(options) and do a framed html-output with all collected subdomain-options

PHP Code:


			
<html>

<head>

<title><?php echo $row[title] ?></title>

<meta name="keywords" content="<?php echo $row[metaauthor] ?>">

<meta name="keywords" content="<?php echo $row[metakeywords] ?>">

<meta name="description" content="<?php echo $row[metadescription] ?>">

<meta name="revisit-after" content="<?php echo $row[metarevisit] ?>">

<meta name="robots" content="<?php echo $row[metarobots] ?>">

</head>

<frameset rows="100%,*" frameborder="NO" border="0" framespacing="0">

<frame name="main" src="<?php echo $target_url ?>">

</frameset>

<noframes>

<body bgcolor="#FFFFFF" text="#000000">

<a href="<?php echo $target_url ?>">Hier klicken um <?php echo $row[title] ?> zu besuchen.</a>

</body>

</noframes>

</html>

7.) it counts how often a subdomain was used

PHP Code:


			
mysql_query("UPDATE usersubdomain SET hits=hits+1 WHERE username='$subhost'") or die (mysql_error());

The file vbsubdomain.php contains a few lines of code
for error-handling.

I hope that my description isn?t to hard to understand and you
will now have a good overview how and why this hack works.
