%Feature PROXY_FACTORY
/*
* \class QgsNetworkAccessManager
* \brief network access manager for QGIS
* \ingroup core
* \since 1.5
*
* This class implements the QGIS network access manager. It's a singleton
* that can be used across QGIS.
*
* Plugins can insert proxy factories and thereby redirect requests to
* individual proxies.
*
* If no proxy factories are there or none returns a proxy for an URL a
* fallback proxy can be set. There's also a exclude list that defines URLs
* that the fallback proxy should not be used for, then no proxy will be used.
*
