There aren't many absolute rules in Web design, but there are 2-3 that you simply MUST follow. Note that folks who brazenly break these rules, while rebels who deserve our respect, never succeed when posting sites to the internet.
So the second rule we'll encounter that cannot be broken relates to what you name your web files.
This rule is simple: do not insert any space into the names of your webpage files. "My Links" might be an easy file name to remember later, but it won't get your links page on the web. Instead, you'd want to eliminate the space between the words and call this page "MyLinks."
So, to recap, your home page must be saved as "index." Only as "index," and as "index" with no typographical whistles and bells. And none of your web file names can contain any spaces.
