Sava can host multiple sites on the same database. Once you have it installed, you can add another site. Each site is contained in a subdirectory with its own settigs, include files, etc. You have to differentiate betweens sites using Domain Name. So I used Localhost and 127.0.0.1.
The page is built off a templates. Templates contain custom sava tags to include dynamic information from SAVA CMS and the static code for things that are common across all pages. Content providers can associate additional information. Templates and other settings appear to be inherited by their children.
