Method	__init__	Undocumented
Method	gotHeaders	Parse the response HTTP headers.

Method	noPage	Close the storage file and errback the waiting `Deferred` with the given reason.
Method	pageEnd	Undocumented

Inherited from HTTPClientFactory:

Instance Variable	deferred	A Deferred that will fire when the content has been retrieved. Once this is fired, the ivars `status', `version', and `message' will be set. (type: Deferred)
Instance Variable	status	The status of the response. (type: bytes)
Instance Variable	version	The version of the response. (type: bytes)
Instance Variable	message	The text message returned with the status. (type: bytes)
Instance Variable	response_headers	The headers that were specified in the response from the server. (type: dict)
Instance Variable	method	The HTTP method to use in the request. This should be one of OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, or CONNECT (case matters). Other values may be specified if the server being contacted supports them. (type: bytes)
Instance Variable	redirectLimit	The maximum number of HTTP redirects that can occur before it is assumed that the redirection is endless. (type: int)
Instance Variable	afterFoundGet	Deviate from the HTTP 1.1 RFC by handling redirects the same way as most web browsers; if the request method is POST and a 302 status is encountered, the redirect is followed with a GET method (type: `bool`)
Method	__repr__	Undocumented
Method	setURL	Undocumented
Method	buildProtocol	Create an instance of a subclass of Protocol.
Method	gotStatus	Set the status of the request on us.
Method	page	Undocumented
Method	clientConnectionFailed	When a connection attempt fails, the request cannot be issued. If no result has yet been provided to the result Deferred, provide the connection failure reason as an error result.
Instance Variable	_redirectCount	The current number of HTTP redirects encountered. (type: int)
Instance Variable	_disconnectedDeferred	A `Deferred` which only fires after the last connection associated with the request (redirects may cause multiple connections to be required) has closed. The result Deferred will only fire after this Deferred, so that callers can be assured that there are no more event sources in the reactor once they get the result.
Method	_waitForDisconnect	Chain onto the _disconnectedDeferred, preserving `passthrough`, so that the result is only available after the associated connection has been closed.
Method	_cancelTimeout	Undocumented

Inherited from ClientFactory (via HTTPClientFactory):

Method	startedConnecting	Called when a connection has been started.
Method	clientConnectionLost	Called when an established connection is lost.

Inherited from Factory (via HTTPClientFactory, ClientFactory):

Class Method	forProtocol	Create a factory for the given protocol.
Method	logPrefix	Describe this factory for log messages.
Method	doStart	Make sure startFactory is called.
Method	doStop	Make sure stopFactory is called.
Method	startFactory	This will be called before I begin listening on a Port or Connector.
Method	stopFactory	This will be called before I stop listening on all Ports/Connectors.
