Robots.txt and Query Strings

Can they block non directory paths?

Anyone know if you can safely block paths like:

User-agent: *
Disallow: /script.php?a=10
Disallow: /script.php?a=11

So anyhting after "/script.php?a=10" does not get indexed, like:

/script.php?a=10&b=11

or can it only be directories?

Thanks

It can be the start of any URL that you like.
So yes, in your example /script.php?a=10&b=11 would be excluded as well.

Thanks Dijkgraaf, I appreciate the tip.
