Post redirect behavior in 5.4
Hi,
I migrated httpClient to 5.4 from 4.5 and see a difference in post redirect behavior. In 4.5, a post request does not automatically follow a 302 response but it seems to do so in 5.4. Is this intended? It is not documented in the migration guide. How do I get back the 4.5 behavior?
Thanks,
Hari.

Thank you for the explanation. Since this is the new standard (RFC 9110), it makes sense for me to just disable redirect for the specific failing request(s) rather than change the client behavior.

Yes, it is.
HttpClient 5.4 conforms to the latest HTTP specification (RFC 91xx)
that differs in redirect behavior definition from older revisions of
the specification.

Replace the standard RedirectExec interceptor with a custom one.
