+/*!
+ \class QDeclarativeNetworkAccessManagerFactory
+ \since 4.7
+ \brief The QDeclarativeNetworkAccessManagerFactory 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 QDeclarativeNetworkAccessManagerFactory and
+ implement the virtual create() method, then assign it to the relevant QML
+ engine using QDeclarativeEngine::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
+ \o 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.
+ \o 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}.
