By default, requests does not support this, but there is a separate package which does - requests-toolbelt. The following classes are provided: class urllib2.

By default, Requests does not retry failed connections. Datacamp has beginner to advanced Python training that programmers of all levels benefit from. Session formerly, session took parameters s.

A realm of None is considered a catch-all realm, which is searched if no other realm fits. Basically to have something in the library, which check if header contains the tchar characters and sends back a warning of exception when not part of it. See the documentation for the constructor.

A subclass may override this method to support more appropriate behavior if needed.

Arguments, return values and exceptions raised are the same as those of which simply calls the method on the currently installed global. The main definitions are located inside the tag. When certifi was not installed, this led to extremely out-of-date certificate bundles when using significantly older versions of Requests. If you require a different encoding, you can manually set the property, or use the raw. Note When performing basic authentication, a instance calls its method. The text encoding guessed by Requests is used when you access r.

If a request times out, a Timeout exception is raised. The supported object types include bytes, file-like objects, and iterables. Requests that produced this error are safe to retry. If I needed to what the reporter of this issue needed to do, I'd probably just use Twill. Such a third party would not have access to the same cookies so would be prevented. See for details of the precise meanings of the various redirection codes. The production rules defined by the specification are clear.
