I am trying to get the value for query string that i have added to the product url.
I have to check that it is redirected from some page like shopping.com or shop.com or buy.com.
Where can i write the code that my query string has value and it is redirected to my product page from shopping.com or shop.com.
My url is --
http://www.mystore.com/p-12020-lg-19...ck.aspx?id=899
Now i want to check that it is coming from the url and has query string value for id = 899,as we are generating our url on the fly from database which is the place where i can check that the url has id value of 899.
