How to tell Goggle that /index.html is my default page

Hi,
I need a consultation. Is there a difference in listing the backlinks of the domain, and domain + index page. For example my site DrugInfo is listed in DMOZ and Google directory with the index page (/index.html). In Google Webmaster Central, Google differentiates the backlinks of the domain and the backlinks of domain+index page.
How to tell Goggle that /index.html is my default page.
Thanks in advance.

 

That's odd, I always thought that index.html was equivalent to just the domain or dir

 

i think you must use 301 redirect for that page . because sitename.com and sitename.com/index.html is the same

 

You can tell all bots that index.html is your index page by adding this line to your .htaccess file

DirectoryIndex index.html

 

Thanks to all for the very important for me suggestions!

 

i think this might be a server related question maybe
