New in Symfony 4.1: 307 and 308 redirections
In web applications is common to use the
301 HTTP status code to make
permanent redirections and the
302 code to make temporary redirections.
However, a problem with these redirection types is that a
POST request is
transformed into a
GET request when doing the redirection for legacy
reasons (redirecting a
POST request didn't work well in old browsers).
In order to solve these issues, the HTTP standard introduced two new status codes:
307(Temporary Redirect): defined in RFC 7231 and similar to
302(Found), except that it does not allow changing the request method from
308(Permanent Redirect): defined in RFC 7538 and similar to
301(Moved Permanently), except that it does not allow changing the request method from
In Symfony 4.1 we added support for these new redirection types by adding a new
keepRequestMethod argument to the
urlRedirectAction() methods of the
RedirectController. You can also use
it as the
keepRequestMethod option in the route definitions:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
route_301: # ... defaults: # ... permanent: true route_302: # ... defaults: # ... permanent: false route_307: # ... defaults: # ... permanent: false keepRequestMethod: true route_308: # ... defaults: # ... permanent: true keepRequestMethod: true
