I think we should stop this thread now. We have put too much efforts in this thread. Also, I would recommend you to read the question first before replying. Understand the question first rather than assuming.
Hey guys, I appreciate all of the responses. I am working with a site that has an affiliate program and they have thousands of affiliate links pointing back to them,many of them being indexed. I would like to implement a robots.txt exclusion to prevent crawlers from accessing URLs with affiliate ID's to clean up search results for this particular domain.
