-- | Redirect to the given route. The redirect will be a temporary redirect to
-- a GET request. This is the appropriate choice for a get-following-post
-- technique, which should be the usual use case. This function currently uses
-- a 302 status code, though the implementation is free to change in the future
-- to an equivalent code with the same semantics (e.g., 303).
--
-- If you want direct control of the final status code, or need a different
-- status code, please use 'redirectWith'.
--
-- Note: According to the HTTP spec, a 302 does /not/ have the semantics
-- described here. However, this has been historically how clients treated a
-- 302. 303 is not understood by older clients, which is why we have opted for
-- a 302. If at some future date it is determined that virtually all clients
-- understand 303, this implementation will switch to that status code.
-- | Redirect to the given route.
-- HTTP status code 303 for HTTP 1.1 clients and 302 for HTTP 1.0
