The RESTeasy implementation of the JAX-RS client library does not seem to support any handling of redirects, despite the underlying ability of Apache HttpClient to do so.
At the very least there are these problems:
1) There is no way to indicate that a proxy class generated via ResteasyWebTarget.proxy should follow redirects.
2) ClientInvoker has some relevant methods but you cannot call the setter "followRedirects" particularly from a proxy and even if you could the getter seems to be totally unreferenced
3) ApacheHttpClient4Engine explicitly forbids it with a TODO
There are multiple threads to the mailing list about this functionality and none of them seem to have any response but silence.
