  class HTTPSessionInstantiator;

  class Net_API HTTPSessionFactory
  
A factory for HTTPClientSession objects. Given a URI, this class creates a HTTPClientSession (for http) or a HTTPSClientSession (for https) for accessing the URI. The actual work of creating the session is done by HTTPSessionInstantiator objects that must be registered with a HTTPSessionFactory. { public: HTTPSessionFactory(); Creates the HTTPSessionFactory.

          HTTPSessionFactory(const std::string& proxyHost, Poco::UInt16 proxyPort);
  
Creates the HTTPSessionFactory and sets the proxy host and port.

          ~HTTPSessionFactory();
  
Destroys the HTTPSessionFactory.

          void registerProtocol(const std::string& protocol, HTTPSessionInstantiator* pSessionInstantiator);
  
Registers the session instantiator for the given protocol. The factory takes ownership of the SessionInstantiator. A protocol can be registered more than once. However, only the instantiator that has been registered first is used. Also, for each call to registerProtocol(), a corresponding call to unregisterProtocol() must be made.

          void unregisterProtocol(const std::string& protocol);
  
Removes the registration of a protocol. Throws a NotFoundException if no instantiator has been registered for the given protocol.

          bool supportsProtocol(const std::string& protocol);
  
Returns true if a session instantiator for the given protocol has been registered.

          HTTPClientSession* createClientSession(const Poco::URI& uri);
  
Creates a client session for the given uri scheme. Throws exception if no factory is registered for the given scheme

          const std::string& proxyHost() const;
  
Returns the proxy host, if one has been set, or an empty string otherwise. Poco::UInt16 proxyPort() const; Returns the proxy port number, if one has been set, or zero otherwise.

          void setProxy(const std::string& proxyHost, Poco::UInt16 proxyPort);
  
Sets the proxy host and port number.

          static HTTPSessionFactory& defaultFactory();
  
Returns the default HTTPSessionFactory.
