Pointing domain to a page in my site

Question

I'm having a directory website with sub-pages for each city. Like for example Newyork will have an address www.directory.com/newyork, LA will have www.directory.com/la

so i want to point the the domain newyorkdirectory.com to www.directory.com/newyork and so for each sub sections... what are the options I have.. can I do this in my code? Is there any way to detect the domain from php and load the content accordingly?

If all i point all the domain's to the site can i detect the incoming domain and refer them to a page? I totally have no idea on this.

Clarification: when people goto the site through newyorkdirectory.com the page www.directory.com/newyork/malls should be accessed through newyorkdirectory.com/malls

Answer 1

so i want to point the the domain newyorkdirectory.com to www.directory.com/newyork

You mean you want all existing "newyorkdirectory.com" links of your website to point to "www.directory.com/newyork"? Or you want to point to "www.directory.com/newyork" when people try to go to "newyorkdirectory.com"?

Second case is impossible if you do not possess domain "newyorkdirectory.com", else you can reroute using Apache .htaccess I think.

Answer 2

Are you in control of the web-server? You can simply make the newyork folder the root for the newyorkdirectory.com domain. If it's coming from somewhere else, you could always drop a quick re-direct script on that domain... i.e. index.php:

<?php
header('Location: http://www.directory.com/newyork');
exit();
?>
