Why don't the landlord use Apache RESIN? However, you can use IIS to use IIS or Apache alias services to point the domain name to the site folder in the Apache or IIS configuration, with the IP. Here I mean the new battle of IIS www.s1.com, port: 80, other configurations enter www.s1.com Site property -Web site-IP address next to the advanced - Edit that default standard, set the host The name is www.s1.com to this, complete the alias of S1, this and the aliasing of the domain name is similar to the new site www.s2.com, port: 80, other slightly here the same S1 configuration, only the host header is changed to WWW .s2.com
To this, the alias control is completed, using www.s1.com and www.s2.com will see different battles, but your ping www.s1.com and www.s2.com IP are the same
Apache: Different from the configured configuration of the virtual host, if it is the need to set NameVirtualHost with IP, if it is a detailed this item NameVirtualHost Site Name
