if it is linked to from a url that specifies a different schema, for example the https: protocol, the search engines would link to and therefore index it separately from the http: specification.

Thank you Phranque.

The reason I have put this question is that I shall be moving my website from [example1.com...] to [example2.com...] and I will have to hence modify all the internal links from my 1200+ pages.

I thought if I may simplify my work by merely removing the "http://example1.com" from the internal links instead of replacing each of those with a "http://example2.com". Doing so, I see links to the page without http prefix

And thankfully, all my pages are on http protocol only. I guess then that this should ok?

Use "/index.html" or simply "/" to link to main page.

I may be misunderstanding, but if you put:

<a href="example.com/index.html">some link text</a>

on your page, then the landing page will be:

http://example.com/example.com/index.html

and thats probably not what you want.

You can put:

<a href="http://example.com/index.html">some link text</a>

or

<a href="/index.html">some link text</a>

or a couple of other variants - but you can't leave off the http as you describe!

Thank you leadegroot and Sevamaster...I have been doing just that now..
