The flash.net package contains classes for sending and receiving from the network, such as URL downloading and Flash Remoting.

	Class	Description
	FileFilter	The FileFilter class is used to indicate what files on the user's system are shown in the file-browsing dialog box that is displayed when the FileReference.browse() method, the FileReferenceList.browse() method is called or a browse method of a File, FileReference, or FileReferenceList object is called.
	FileReference	The FileReference class provides a means to upload and download files between a user's computer and a server.
	FileReferenceList	The FileReferenceList class provides a means to let users select one or more files for uploading.
	LocalConnection	The LocalConnection class lets you create a LocalConnection object that can invoke a method in another LocalConnection object.
	NetConnection	The NetConnection class creates a bidirectional connection between a Flash Player or AIR an AIR application and a Flash Media Server application or between a Flash Player or AIR an AIR application and an application server running Flash Remoting.
	NetStream	The NetStream class opens a one-way streaming connection between an AIR or Flash Player application and Flash Media Server, or between an AIR or Flash Player application and the local file system.
	NetStreamInfo	The NetStreamInfo class specifies the various Quality of Service (QOS) statistics related to a NetStream object and the underlying streaming buffer for audio, video, and data.
	NetStreamPlayOptions	The NetStreamPlayOptions class specifies the various options that can be passed to the NetStream.play2() method.
	NetStreamPlayTransitions	The NetStreamPlayTransitions class specifies the valid strings that you can use with the NetStreamPlayOptions.transition property.
	ObjectEncoding	The ObjectEncoding class is used in defining serialization settings in classes that serialize objects (such as FileStream, NetStream, NetConnection, SharedObject, and ByteArray) to work with prior versions of ActionScript.
	Responder	The Responder class provides an object that is used in NetConnection.call() to handle return values from the server related to the success or failure of specific operations.
	SharedObject	The SharedObject class is used to read and store limited amounts of data on a user's computer or on a server.
	SharedObjectFlushStatus	The SharedObjectFlushStatus class provides values for the code returned from a call to the SharedObject.flush() method.
	Socket	The Socket class enables code to make socket connections and to read and write raw binary data.
	URLLoader	The URLLoader class downloads data from a URL as text, binary data, or URL-encoded variables.
	URLLoaderDataFormat	The URLLoaderDataFormat class provides values that specify how downloaded data is received.
	URLRequest	The URLRequest class captures all of the information in a single HTTP request.
	URLRequestDefaults	The URLRequestDefaults class includes static properties that you can set to define default values for the properties of the URLRequest class.
	URLRequestHeader	A URLRequestHeader object encapsulates a single HTTP request header and consists of a name/value pair.
	URLRequestMethod	The URLRequestMethod class provides values that specify whether the URLRequest object should use the POST method or the GET method when sending data to a server.
	URLStream	The URLStream class provides low-level access to downloading URLs.
	URLVariables	The URLVariables class allows you to transfer variables between an application and a server.
	XMLSocket	The XMLSocket class implements client sockets that let the Flash Player or AIR application communicate with a server computer identified by an IP address or domain name.
