301 redirect all except robots.txt file

Question

In my htaccess I have redirect all pages from my domain to main page.

I would like just to exclude from this redirect robots.txt file and url like: http://www.example.com/?123 to http://www.example.com/. Is it possible?

I have tried following .htaccess rules:

RewriteRule .+ http://www.example.com [r=301,nc,l]
