allowing google bot only to index URL with parameters

[ulmudmezig]

Hello,

I have made a mistake and google indexed 2 different URLs with same content

www.site.com/page.php?c=2&t=10
and
www.site.com/page.php?c=2

are both indexed and have the same content. I want to keep
www.site.com/page.php?c=2&t=10

and remove the other one from the google index. Since i have like 300 pages like this i dont want to do it manually. Is there any regular expression that i can put in to robots.txt to do it.

Thanks

Very interesting situation. I cant think of a regular robots.txt expression. It may be easier to deal with this using a 301 redirect in htaccess.
