I am attempting to host multiple sites on my small Wamp server (Home windows),

I've added new virtual hosts in "C:WINDOWSsystem32driversetchosts" :

127.0.0.1 localhost
127.0.0.1 bitrix

I produced a brand new folder "C:wampbitrix" for everyone my second project's files. And than add this code in httpd.conf:

    NameVirtualHost 127.0.0.1
<VirtualHost 127.0.0.1>
    ServerName localhost
    DocumentRoot 'C:\wamp\www'
</VirtualHost>

<VirtualHost 127.0.0.1>
    ServerName bitrix
    DocumentRoot 'C:\wamp\bitrix'
</VirtualHost>

however when i am attempting to access http://localhost or http://bitrix i am getting "403 Forbidden" error.

If a person knows where's my mistake help me :)

Can't you simply place them both within different folder from the htdocs directory?

MAMP -> htdocs
