.inc include files and default index.shtml serving from a Mac to Internet Explorer

Hi,

Is there anything which necessarily must be done to make .shtml pages with
include files function properly on Macs?

Will a Mac server serve index.shtml files as the default homepage to a site,
when viewed through Internet Explorer?

In order for .inc files to be used the pages in which they are embedded must
use the .shtml extension, is this correct?


thank you
