I want to disallow with robots.txt from indexing my site available with all domain endings (co.uk, in, pl, de, nl ...etc), but allow only with com-ending.
I haven't physical access to htaccess file (affected is a blogger.com blog), otherwise i would just redirect all endings to the wishful one. But while i can't redirect, i want even to disallow all endings, beside of .com.
Sure, i could just create a list with all endings and disallow them one by one, but it seems to me, there must be a smarter solution for this issue, which i haven't found till now.
How to do that?
