The main (starting) page of your web site must have a particular name, it must be named either "default" or "index" with a valid file name extension.
Valid combinations of names and extensions for a starting page are shown to the right:
Page Name / Processing
HTML only
SSI
MGI
default
default.htm
default.html
default.ssi
default.shtml
default.mgi
default.mhtml
index
index.htm
index.html
index.ssi
index.shtml
index.mgi
index.mhtml
Other web pages
Pages, other than the main starting page, can be named anything you like, but they still need the proper filename extension in order to be processed correctly. See the extension chart below:
Page Name Extensions
The extension of the filename determines what type of processing will be done to the page before it is sent from the web server.
If you don't use the proper extension the processing you expect won't occur.
Page Type / Extionsions
3 character
alternate
HTML (no processing)
.htm
.html
SSI used on page
.ssi
.shtml
MGI used on page
.mgi
.mhtml
What if I want both SSI
and MGI on one page?
You can't. The filename extension determines the type of processing that will be done. You can only choose one or the other, not both.
