Trying to Redirect. 302 Error. HTTP CLIENT 4.1.1

Edited:- Updated One

What's wrong with this code. Now I am getting error on setRedirectStrategy as

The method setRedirectStrategy(new DefaultRedirectStrategy(){}) is undefined for the type DefaultHttpClient

and error on DefaultRedirectStrategy as

DefaultRedirectStrategy cannot be resolved to a type

and error on super as the same as above one

DefaultRedirectStrategy cannot be resolved to a type

And I am trying t开发者_运维技巧o redirect as I am always getting 302 error. So is this the right way to do it. Any example will be appreciated..

I think it's quite simple: you're missing HttpContext in your import statement at the top of this code block. Add org.apache.http.protocol.HttpContext somewhere in the comma-separated import list.

As for whether this is the right way to do it, what's it? Can you say more about your application?

I think you can use

final DefaultRedirectStrategy instance =new LaxRedirectStrategy();
httpClientBuilder.setRedirectStrategy(instance);

if you just want to override 302
