I am a web developer, and I have several development environments, including local to my machine, and I set them up with different subdomains thusly: http://local.mywebsite.com - my local machine http://dev.mywebsite.com - development site on a real server http://www.mywebsite.com - live website I have a script called script1.php that exists on my local site and my development site, and I have visited both urls, so they are in my history. Why, when I type http://dev.mywebsite.com/script... does it ALWAYS suggest http://local.mywebsite.com/script1.php as the first suggestion?!? If I specify the subdomain and the domain, it should never suggest something on a different subdomain, so why does it happen?
