My site http://www.quickhaggle.com is built on Yii Framework. I have notice that a page is accessed through different URLs which is actually creating "duplicate content issue" for the site.
For example
The original page:- http://www.quickhaggle.com/offer/I-am-looking-for-a-Wedding-Planner,-i-am-a-Financial-Adviser-26.htm
Which is also accessible through the following URLs.
http://www.quickhaggle.com/offer/I-am-looking-for-a-Wedding-Planner,-i-am-a-Financial-Adviser-26.htm?route=offer%2FI-am-looking-for-a-Wedding-Planner%2C-i-am-a-Financial-Adviser-26.htm&area=New+Zealand&MPublicMessagesForm_page=2
http://www.quickhaggle.com/offer/I-am-looking-for-a-Wedding-Planner,-i-am-a-Financial-Adviser-26.htm?route=offer%2FI-am-looking-for-a-Wedding-Planner%2C-i-am-a-Financial-Adviser-26.htm&area=New+Zealand&MPublicMessagesForm_page=3
http://www.quickhaggle.com/offer/I-am-looking-for-a-Wedding-Planner,-i-am-a-Financial-Adviser-26.htm?route=offer%2FI-am-looking-for-a-Wedding-Planner%2C-i-am-a-Financial-Adviser-26.htm&area=New+Zealand&MPublicMessagesForm_page=4
Other Variation
What entries I need to mention in the Robots.txt file to stop google from indexing all these variations. I will appreciate your help in this matter.
Thank you in advance.
