URL Rewriting Module in asp.net

Hello, I need a URL rewriting module that will work with n number of query strings. Means the URLS define in the rewrtie rule not be fixed. For e.g if you define the rewrite rule with two query strings like [login to view URL] for the page [login to view URL] so if user pass only one query string i.e. [login to view URL] then it must rewrite then url as [login to view URL] so in this case it will fetch the productname from DB. if user pass three query strings like [login to view URL] then it must rewrite the url as [login to view URL] if user pass four query strings like [login to view URL] then it must rewrite the url as [login to view URL] so number of query string is not sure it can be 1 or it can be 15 or 30 So the module must be smart and it will rewrite the url according to the querystrings For e.g below site [login to view URL] i pass three query string and it rewrite the url as [login to view URL] if i will pass one query string [login to view URL] then it will rewrite the url as [login to view URL] so i want this kind of module that will write the url according to number of querystrings. Hopefully it will clear the requriements. if you have any doubt then please ask to me. I need to complete this project within 3-4 days. So Please only serious bidders apply for this. if you have any relative sample for this then pl. provide the link. Thanks
