mod rewrite everything after domain into get

Question

How can I rewrite everything after the domain name into get if it is not already get?

For example : example.com/blah/blah.blah

will become example.com/?blah/blah

Answer 1

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* /index.php?$0 [QSA]

But this solution has some issues, @anubhava's is better ;-)
