I use pmwiki for my website. By mistake, I missed doing url canonicalization for my home page. Today I see Google has saved 2 cached copy for my home page one for 'www.mydomain.com' - on 21 nov, 09 another for 'www.mydomain.com/index.html' - on 19th Nov, 09 Now I want to remove the url 'www.mydomain.com/index.html' from Google Webmaster tool. How do I do that? I know that for removing a page I need to block that page from googlebot. But it is the same page as my home page. I'm confused. Please advice. Thanks,
