MVC HttpWebResponse 404 error.

Question

Hi ,
       Am trying to post data from one view to another view using httpWebrequest and getting response from that view using httpwebresponse.

        I did the same in asp.net application it works fine for two pages in the same application.
but when am trying to do the same in MVC to post data to next page and to get response am getting 404 error page not found, but (if i pressed ctrl + link (which i specified in httpwebrequest) it redirects properly) so there is no problem with my link y am getting this error.. 

I have attached the image which shows my code.

Thanks in advance....
