[jira] [Created] (HTTPCLIENT-1716) DefaultRedirectStrategy seems to
disregard HTTP spec for PUT/POST/DELETE request redirects
Dariusz Kordonski created HTTPCLIENT-1716:
---------------------------------------------
Summary: DefaultRedirectStrategy seems to disregard HTTP spec for PUT/POST/DELETE request redirects
Key: HTTPCLIENT-1716
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1716
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient
Affects Versions: 5.0 Alpha1
Reporter: Dariusz Kordonski
Observed on {{trunk}} branch that has 5.0-alpha2-SNAPSHOT mvn version.
The docs for {{DefaultRedirectStrategy}} correctly state:
{quote}
his strategy honors the restrictions on automatic redirection of entity enclosing methods such as POST and PUT imposed by the HTTP specification. {@code 302 Moved Temporarily}, {@code 301 Moved Permanently} and {@code 307 Temporary Redirect} status codes will result in an automatic redirect of HEAD and GET methods only. POST and PUT methods will not be automatically redirected as requiring user confirmation.
{quote}
(NB: in fact to be more precise I think DELETE requests should also be **not** automatically redirected)
However the actual implementation does not seem to follow this, whereby {{isRedirected}} pretty much lets all requests through:
{code}
switch (statusCode) {
case HttpStatus.SC_MOVED_PERMANENTLY:
case HttpStatus.SC_MOVED_TEMPORARILY:
case HttpStatus.SC_SEE_OTHER:
case HttpStatus.SC_TEMPORARY_REDIRECT:
return true;
default:
return false;
}
{code}
A simple failing test case that confirms the problem for a PUT request resulting with 302 (PUT should only be redirected automatically for 303):
{code}
@Test
public void testIsRedirectedForTemporaryRedirectPut() throws Exception {
final DefaultRedirectStrategy redirectStrategy = new DefaultRedirectStrategy();
final HttpResponse response = new BasicHttpResponse(HttpVersion.HTTP_1_1,
HttpStatus.SC_TEMPORARY_REDIRECT, "Temporary Redirect");
response.addHeader("Location", "http://localhost/stuff");
final HttpContext context = new BasicHttpContext();
assertFalse(redirectStrategy.isRedirected(new HttpPut("http://localhost/"), response, context));
}
{code}
