This class of status code indicates the client must take additional action to complete the request. Many of these status codes are used in URL redirection. [2]A user agent may carry out the additional action with no user interaction only if the method used in the second request is GET or HEAD.

Twisted can integrate with foreign event loops, such as those of GTK+, Qt and Cocoa (through PyObjC). This allows using Twisted as the network layer in graphical user interface (GUI) programs, using all of its libraries without adding a thread-per-socket overhead, as using Python's native library would. A full-fledged web server can be ...
Network timeout preventing a Web browser from loading a page. In telecommunications and related engineering (including computer networking and programming), the term timeout or time-out has several meanings, including: A network parameter related to an enforced event designed to occur at the conclusion of a predetermined elapsed time.
When the rate has been reduced in response to an adverse event, it usually does not remain at that reduced level forever. If no adverse events are observed for some period of time, often referred to as the recovery time or cooling-off period, the rate may be increased again. The time period that must elapse before attempting to increase the ...
408 Request Timeout: The HTCPCP server is unable to make tea for a timeout and forbidden actions. 418 I'm a teapot: The HTCPCP server is a teapot; the resulting entity body "may be short and stout" (a reference to the song "I'm a Little Teapot").

A callback can be used for event handling. Often, consuming code registers a callback for a particular type of event. When that event occurs, the callback is called. Callbacks are often used to program the graphical user interface (GUI) of a program that runs in a windowing system. The application supplies a reference to a custom callback ...
Do not make multi-threaded requests. Wait for one server request to complete before beginning another. Back off upon receiving errors from the server. Errors such as timeouts are often an indication of heavy server load. Use a sequence of increasingly longer delays between repeated requests. Make use of assertion to ensure your bot is logged in.
