twisted.web.client.RedirectAgent

class documentation

class RedirectAgent: (source)

Implements interfaces: twisted.web.iweb.IAgent

An Agent wrapper which handles HTTP redirects.

The implementation is rather strict: 301 and 302 behaves like 307, not redirecting automatically on methods different from GET and HEAD.

See BrowserLikeRedirectAgent for a redirecting Agent that behaves more like a web browser.

Parameters
redirectLimit	The maximum number of times the agent is allowed to follow redirects before failing with a `error.InfiniteRedirection`.
sensitiveHeaderNames	An iterable of `bytes` enumerating the names of headers that must not be transmitted when redirecting to a different origins. These will be consulted in addition to the protocol-specified set of headers that contain sensitive information.
Present Since
11.1

Method	`__init__`	Undocumented
Method	`request`	Send a client request following HTTP redirects.

Method	`_handleResponse`	Handle the response, making another request if it indicates a redirect.
Method	`_resolveLocation`	Resolve the redirect location against the request URI.
Class Variable	`_redirectResponses`	A `list` of HTTP status codes to be redirected for GET and HEAD methods.
Class Variable	`_seeOtherResponses`	A `list` of HTTP status codes to be redirected for any method and the method altered to GET.
