I am looking to replace the text of the url displayed when users try to access my site with an account code like nom.mlxhelp.com, while this works if the users are coming from a production site, I can no longer get it to work on the server itself. I am kind of at a loss as to why it doesn't work anymore. the existing redirect is like below.. 
 
if (!(substr($Request->ServerVariables("SERVER_NAME")->item(),0,3) eq 
+"www") && !(substr($Request->ServerVariables("SERVER_NAME")->item(),0
+,3) eq "mlx") && !(lc($Request->ServerVariables("SERVER_NAME")->item(
+)) eq "localhost"))
$Request->ServerVariables("SERVER_NAME")->item() =~ /([\w+]*)\./;
      $str .= "<inputH name=\"site\" value=\"".$1."\"/>";

this works for redirecting from a production site, but what I want is to be able to input sitecode.mysiteurl.com and have it reach the site. I don't recall changing anything that would have broken it, but am not sure why it no longer works.
