I am getting exception "The server committed a protocol violation. Section=ResponseStatusLine" while downloading dll.

I used the bellow solution found on google.

<system.net>
   <settings>
     <httpWebRequest useUnsafeHeaderParsing="true" />
   </settings>
 </system.net>

It solved the above exception. but causing some other exception can any one please help to solve this issue.
