Httpclient 4, error 302. How to redirect?

Question

I want to access one site that first requires an (tomcat server) authentication and then log in with a POST request and keep that user to see the site\'s pages. I use Httpcl

You have to implement custom redirection handler that will indicate that response to POST is a redirection. This can be done by overriding isRedirectRequested() method as shown below.

DefaultHttpClient client = new DefaultHttpClient();
client.setRedirectHandler(new DefaultRedirectHandler() {                
    @Override
    public boolean isRedirectRequested(HttpResponse response, HttpContext context) {
        boolean isRedirect = super.isRedirectRequested(response, context);
        if (!isRedirect) {
            int responseCode = response.getStatusLine().getStatusCode();
            if (responseCode == 301 || responseCode == 302) {
                return true;
            }
        }
        return isRedirect;
    }
});

In later version of HttpClient, the class name is DefaultRedirectStrategy, but similar solution can be used there.
