Michael Lee commented on HTTPCLIENT-2118:
-----------------------------------------
The headers log does not tell the whole story. As mentioned in the original
description of this issue, 5.0.x returned a NoHttpResponseException. After
that, it retried the GET request and then got a 403. You can refer to the
attached test_output.txt that captured this event/exception:
{noformat}

On the other hand, 4.1.x handled the redirect, did not throw the
ResponseException and returned 304.

> Key: HTTPCLIENT-2118
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2118
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (classic), HttpClient (Windows)
> Affects Versions: 5.0.2
> Environment: Microsoft Windows 10 version 2004 [10.0.19041.508]
> Oracle JDK 11.0.8
> Reporter: Michael Lee
> Priority: Major
> Attachments: demo.zip, headers.log, test_output.txt

>
> My application reuses an instance of CloseableHttpClient to retrieve the
> content from a list of URLs. After upgrading HttpClient from 4.5.x to 5.0.2
> (also 5.0 and 5.0.1), it always gets a NoHttpResponseException followed by a
> response code of 403 for a particular URL in the list. When using 4.5.x, it
> always gets a 200 or 304 for that particular URL.
> The behavior may be different if the order of the URLs in the list is changed.
> To illustrate the problem, I have extracted code from my application into the
> sample Maven project attached. In the JUnit test, testHttpClient4() will get
> either 200 or 304 for all the URLs. On the other hand, testHttpClient5()
> always gets 403 for the last URL in the list. In this project, I
> intentionally added a If-Modified-Since header with the value being current
> time minus 1 minute so that we should get a 304 from most of the URLs.
> Can you investigate if this is really an obscure bug or an undocumented
> behavior change related to how CloseableHttpClient handles redirects?
> Thanks.
