---------------------------------------
Summary: A request retry upon redirect is incorrectly flagged as a
circular redirect
Key: HTTPCLIENT-2333
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2333
Project: HttpComponents HttpClient
Issue Type: Bug
Affects Versions: 5.3.1
Reporter: Teresa Tang
Attachments: NullHandler.java, TestRedirects.java
When a request is redirected and then needs to be retried, the retry is treated
as a circular redirect. If circular redirects are not allowed, an error is
thrown:
{code:java}

Please see testRetryUponRedirect in TestRedirects.java for an example.
NullHandler.java will return a bad response only for the first redirected
request (files attached)
