\class QQmlNetworkAccessManagerFactory
\since 5.0
\inmodule QtQml
\brief The QQmlNetworkAccessManagerFactory class creates QNetworkAccessManager instances for a QML engine.
A QML engine uses QNetworkAccessManager for all network access.
By implementing a factory, it is possible to provide the QML engine
with custom QNetworkAccessManager instances with specialized caching,
proxy and cookies support.
To implement a factory, subclass QQmlNetworkAccessManagerFactory and
implement the virtual create() method, then assign it to the relevant QML
engine using QQmlEngine::setNetworkAccessManagerFactory().
Note the QML engine may create QNetworkAccessManager instances
from multiple threads. Because of this, the implementation of the create()
method must be \l{Reentrancy and Thread-Safety}{reentrant}. In addition,
the developer should be careful if the signals of the object to be
returned from create() are connected to the slots of an object that may
be created in a different thread:
\list
\li The QML engine internally handles all requests, and cleans up any
QNetworkReply objects it creates. Receiving the
QNetworkAccessManager::finished() signal in another thread may not
provide the receiver with a valid reply object if it has already
been deleted.
\li Authentication details provided to QNetworkAccessManager::authenticationRequired()
must be provided immediately, so this signal cannot be connected as a
Qt::QueuedConnection (or as the default Qt::AutoConnection from another
thread).
\endlist
For more information about signals and threads, see
\l {Threads and QObjects} and \l {Signals and Slots Across Threads}.
The \l {Qt Quick 1} version of this class is named QDeclarativeNetworkAccessManagerFactory.

/*!
\fn QNetworkAccessManager *QQmlNetworkAccessManagerFactory::create(QObject *parent)
Creates and returns a network access manager with the specified \a parent.
This method must return a new QNetworkAccessManager instance each time
it is called.
Note: this method may be called by multiple threads, so ensure the
implementation of this method is reentrant.
