Correct way to exclude all dynamic pages under one url?

[jackgordon]

Hello
I have a page, proddetail.php. I want to exclude all the dynamic pages that run off that url, using robots.txt file.

eg.
proddetail.php?prod=1
proddetail.php?prod=2
proddetail.php?prod=3
proddetail.php?prod=4
proddetail.php?prod=5

and so on.....

What is the correct and easiest way to write this in the robots.txt file?

Thanks
Jack

Disallow:

/proddetail.php?

This disallows any URL starting /proddetail.php, and which includes a question mark, and anything else after it.
