Trying to Redirect. 302 Error. HTTP CLIENT

What's wrong with this code. I am getting error on setRedirectStrategy and HttpContext as cannot be resolved to a type. And I am trying to redirect as I am always getting 302 error. So is this the right way to do it. Any example will be appreciated..

Fix your imports. It's missing a few classes.

Edited:- Updated One

After Some modifications in my code, Now I am getting error on setRedirectStrategy as

and error on DefaultRedirectStrategy as

and If I am adding this import to resolve the DefaultDirectStrategy error than I am getting red line on this import as

and error on super as the same as above one

And I am not able to know, what is wrong in this code. Any help will be appreciated. And I am trying to redirect as I am always getting 302 error. So is this the right way to do it. Any example will be appreciated..

DefaultRedirectStrategy is available since HttpClient 4.1. I suggest you upgrade your library.
