Preventing HttpClient 4 from following redirect

Question

I\'m connecting to my AppEngine application using the Apache HttpComponents library. In order to authenticate my users, I need to pass an authentication token along to the

Answer 1

Try using a RedirectHandler. That may require extending DefaultHttpClient to return your custom implementation from createRedirectHandler().

Answer 2

The RedirectHandler seem to be deprecated, I managed to disable automatically following the redirect responses by changing the default RedirectionStrategy for the DefaultHttpClient liks this:

httpClient.setRedirectStrategy(new RedirectStrategy() {
        @Override
        public boolean isRedirected(HttpRequest httpRequest, HttpResponse httpResponse, HttpContext httpContext) throws ProtocolException {
            return false;
        }

        @Override
        public HttpUriRequest getRedirect(HttpRequest httpRequest, HttpResponse httpResponse, HttpContext httpContext) throws ProtocolException {
            return null;
        }
    });

On the downside, this tie us to a specific implementation of the HttpClient but it does the job.

Answer 3

a quick google presented: http://hc.apache.org/httpclient-3.x/redirects.html

Answer 4

With the Version 4.3.x of HttpClient its directly in the clientBuilder.

so when u build your Client use:

CloseableHttpClient client = clientBuilder.disableRedirectHandling().build();

I know its an old question but I had this problem too and want to share my solution.

Answer 5

You can do it with the http params:

final HttpParams params = new BasicHttpParams();
HttpClientParams.setRedirecting(params, false);

The method has no javadoc, but if you look at the source you can see it sets:

HANDLE_REDIRECTS

which controls:

Defines whether redirects should be handled automatically
