FollowRedirect
Client middleware to follow redirect responses.
Client middleware to follow redirect responses.
A 301 or 302 response is followed by: - a GET if the request was GET or POST - a HEAD if the request was a HEAD - the original request method and body if the body had no effects - the redirect is not followed otherwise
A 303 response is followed by: - a HEAD if the request was a HEAD - a GET for all other methods
A 307 or 308 response is followed by: - the original request method and body, if the body had no effects - the redirect is not followed otherwise
Whenever we follow with a GET or HEAD, an empty body is sent, and all payload headers defined in https://tools.ietf.org/html/rfc7231#section-3.3 are stripped.
If the response does not contain a valid Location header, the redirect is not followed.
Headers whose names match
sensitiveHeaderFilterare not exposed when redirecting to a different authority. -
