Redirection

Falcon defines a set of exceptions that can be raised within a middleware method, hook, or responder in order to trigger a 3xx (Redirection) response to the client. Raising one of these classes short-circuits request processing in a manner similar to raising an instance or subclass of HTTPError

Redirects

exception falcon.HTTPMovedPermanently(location) [source]

301 Moved Permanently.

The 301 (Moved Permanently) status code indicates that the target resource has been assigned a new permanent URI.

Note

For historical reasons, a user agent MAY change the request method from POST to GET for the subsequent request. If this behavior is undesired, the 308 (Permanent Redirect) status code can be used instead.

See also: https://tools.ietf.org/html/rfc7231#section-6.4.2

Parameters: location (str) – URI to provide as the Location header in the response.
exception falcon.HTTPFound(location) [source]

302 Found.

The 302 (Found) status code indicates that the target resource resides temporarily under a different URI. Since the redirection might be altered on occasion, the client ought to continue to use the effective request URI for future requests.

Note

For historical reasons, a user agent MAY change the request method from POST to GET for the subsequent request. If this behavior is undesired, the 307 (Temporary Redirect) status code can be used instead.

See also: https://tools.ietf.org/html/rfc7231#section-6.4.3

Parameters: location (str) – URI to provide as the Location header in the response.
exception falcon.HTTPSeeOther(location) [source]

303 See Other.

The 303 (See Other) status code indicates that the server is redirecting the user agent to a different resource, as indicated by a URI in the Location header field, which is intended to provide an indirect response to the original request.

A 303 response to a GET request indicates that the origin server does not have a representation of the target resource that can be transferred over HTTP. However, the Location header in the response may be dereferenced to obtain a representation for an alternative resource. The recipient may find this alternative useful, even though it does not represent the original target resource.

Note

The new URI in the Location header field is not considered equivalent to the effective request URI.

See also: https://tools.ietf.org/html/rfc7231#section-6.4.4

Parameters: location (str) – URI to provide as the Location header in the response.
exception falcon.HTTPTemporaryRedirect(location) [source]

307 Temporary Redirect.

The 307 (Temporary Redirect) status code indicates that the target resource resides temporarily under a different URI and the user agent MUST NOT change the request method if it performs an automatic redirection to that URI. Since the redirection can change over time, the client ought to continue using the original effective request URI for future requests.

Note

This status code is similar to 302 (Found), except that it does not allow changing the request method from POST to GET.

See also: https://tools.ietf.org/html/rfc7231#section-6.4.7

Parameters: location (str) – URI to provide as the Location header in the response.
exception falcon.HTTPPermanentRedirect(location) [source]

308 Permanent Redirect.

The 308 (Permanent Redirect) status code indicates that the target resource has been assigned a new permanent URI.

Note

This status code is similar to 301 (Moved Permanently), except that it does not allow changing the request method from POST to GET.

See also: https://tools.ietf.org/html/rfc7238#section-3

Parameters: location (str) – URI to provide as the Location header in the response.
