Michael Osipov updated HTTPCLIENT-2144:
---------------------------------------
Description:
Given: A request with content-type „application/x-www-form-urlencoded;
charset=ISO-8859-1“. When an http status code of 307 is received, then the
charset of the content-type header is altered to UTF-8 and the body is
re-encoded in the following transmission.
The log snippet shows that the body changes from
"echotext=TEST%F6TEST"
to
"echotext=TEST%C3%B6TEST".

> Key: HTTPCLIENT-2144
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2144
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Reporter: Andrea
> Priority: Major
>
> Given: A request with content-type „application/x-www-form-urlencoded;
> charset=ISO-8859-1“. When an http status code of 307 is received, then the
> charset of the content-type header is altered to UTF-8 and the body is
> re-encoded in the following transmission.
>
> The log snippet shows that the body changes from
> "echotext=TEST%F6TEST"
> to
> "echotext=TEST%C3%B6TEST".
>
> HttpClient Version: 4.5.13
> h3. code snippet:

> CloseableHttpClient httpclient =

> LaxRedirectStrategy()).build();
> HttpPost httpPost = new

> Testservlet responds with http status 307
> List<BasicNameValuePair> nvps = new ArrayList<>();
> nvps.add(new BasicNameValuePair("echotext", "TESTöTEST"));
> httpPost.setEntity(new UrlEncodedFormEntity(nvps,
> Charset.forName("ISO-8859-1")));
