It's not DNS. If you're sure there's no htaccess files in place, check your content (even that stored in a database) for anything that might be altering data based on referrer. This simple test shows what I mean: Airy:~ user$ curl -e 'http://google.com' csulb.edu <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>301 Moved Permanently</title> </head><body> <h1>Moved Permanently</h1> <p>The document has moved <a href="http://www.couchtarts.com/media.php";>here</a>.</p> </body></html> Running curl without the -e argument gives the proper site contents.
