Subject [jira] [Created] (HTTPCLIENT-1452) in case of a redirect a wrong host param is set to http header

Lars Bachmann created HTTPCLIENT-1452:
-----------------------------------------

             Summary: in case of a redirect a wrong host param is set to http header
                 Key: HTTPCLIENT-1452
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1452
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient
            Reporter: Lars Bachmann


The following url will lead to an circular redirect and an CircularRedirectException in the
end:
http://it.bing.com/

The reason is that http://it.bing.com will redirect to http://www.bing.com but the header
param "host" is not set to the new host (bing.com), instead the host param of the original
(it.bing.com) request is used. In the end the redirect request will not call http://www.bing.com
but instead http://it.bing.com which is the same location like the original url and will end
up in a circular dead lock.

The fix would be after copying all header params from the original request to the redirect
request, to override the host param with the value of the redirect request

The class to adjust is: org.apache.http.impl.client.DefaultRequestDirector.java

The problem is also adressed here:
