PHP Site Definition

Greetings! I accidentally deleted my site definition in DW CS4 and now can't remember how to define the url of the site's root folder. The site displays properly in DW's File tab and the pages display properly in design view but when I F12 to display in IE8 I get this; Object not found! The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again. If you think this is a server error, please contact the webmaster. Error 404 localhost 12/21/11 19:49:44 Apache/2.2.21 (Win32) mod_ssl/2.2.21 OpenSSL/1.0.0e PHP/5.3.8 mod_perl/2.0.4 Perl/v5.10.1 The site is located in c:\xampp\htdocs\Milica I thought the url was http://localhost/xampp/htdocs/Milica but it doesn't work. Any suggestions? Do I have to change something in the xampp settings? Is the url wrong? Thanks!
