How to block these urls

[anne10]

This is my url,

mydomain/Home.do?parameter=addToCart&productID=10485&quantity=1

The Quantity and Productid varies

How could I block these urls in Robots.txt

[cuiyj]

Add below text into your Robots.txt (* is wildcard which is supported by google, bing and yahoo)

Disallow: /Home.do?parameter=addToCart*productID=*quantity=*

[tangor]

Your product pages are already indexed, correct? Why allow any "addToCart" links?

Disallow: /Home.do?parameter=addToCart

Should stop all those links from indexing...

These urls are not getting indexed but showing empty redirects in Google webmaster tool.
