Robots file - disallow dirs

Hi guys,

I tried to ban the search engines from accessing my shopping cart pages but I have just discovered that google has indexed many of my cart pages?

example:
www.domainname.com.au/store/cart/phpcart.php?aaaaaaaa


my robots file looks like this and is placed in my domains root:

User-agent: *
Disallow: /cgi-bin/
Disallow: /CMS/
Disallow: /store/cart/
Disallow: /captcha/

Any ideas why it didnt work and what I can do?

try this:

Disallow: /store/cart

Some crawlers see the following "/" telling it to ignore the "index".php file etc... if you want to deny the entire dir. try omitting the following /
