HTTPREQUEST not giving expected result

ASP.NET

I am crawling a website.
The url that i am crawling is "http://www.dealsandyou.com/catalog/product/citysitedeal/productId/8060".
This url shows ahmedabad links when opened in browser. ie. link to first product BlackBerry Smartphones is "http://www.dealsandyou.com/blackberry-smartphones-ahmedabad-26092011.html". But when u read this url in asp.net it always gives data of other cities as "http://www.dealsandyou.com/bluedio-stereo-i4-headset-othercities-29092011.html". That is the products for other cities. I cant understand y is it show. Please help me & give me some solution for this.
My source code is somewhat like :

 private static HttpWebRequest _request;
 private static HttpWebResponse response;
 StreamReader strreader = null;

 _request = (HttpWebRequest)WebRequest.Create("http://www.dealsandyou.com/catalog /product/citysitedeal/productId/8060");
            
 response = (HttpWebResponse)_request.GetResponse();

             
 //create a streamreader object from the response 
 strreader = new StreamReader(response.GetResponseStream());

//reading data in string. This string always give data of other cities
 string strdata = strreader.ReadToEnd();

You can also check for "http://www.dealsandyou.com/catalog/product/citysitedeal/productId/8085". That is the url for banglore products. It will also show other cities data when crawled.

Please help me. Its very urgent.
