For example, the following URIs are formatted correctly:

• rtmp://www.myCompany.com/myMainDirectory/groupChatApp/HelpDesk

• rtmp:/sharedWhiteboardApp/June2002

p1 ... pN Optional parameters of any type to be passed to the application specified in

targetURI. If the application is unable to process the parameters in the order in which they are

received, NetConnection.onStatus is invoked with the code property set to

NetConnection.Connect.Rejected.

Returns

A Boolean value of true if you passed in a valid URI, false otherwise. (To determine if the

connection was successfully completed, use

NetConnection.onStatus.).

Description

Method; connects to an application on the Flash Communication Server. This method can also

be used to communicate with an application server. For information, see Using Flash Remoting.

If you want to use this connection for publishing or playing audio or video in real time, or to

publish or play previously recorded audio or video streams, you must connect to the Flash

Communication Server and then create a NetStream object within this NetConnection object.

For more information, see the “NetStream (object)” entry.

If you want to use this connection for synchronizing data among multiple clients or between the

client and a server, you must connect to the Flash Communication Server and then create a

remote shared object within this NetConnection object. For more information, see the

“SharedObject (object)” entry.

When you call this method, the

NetConnection.onStatus event handler is invoked with an

information object that specifies whether the connection succeeded or failed. For more

information, see the example below and

NetConnection.onStatus. If the connection is

successful,

NetConnection.isConnected is set to true.

Because of network and thread timing issues, it is better to place a

NetConnection.onStatus

handler in a script before a

NetConnection.connect method. Otherwise, the connection might

complete before the script executes the onStatus handler initialization. Also, all security checks

are made within the

connect method, and notifications will be lost if the onStatus handler is

not yet set up.

If the specified connection is already open when you call this method, an implicit

NetConnection.close method is invoked, and then the connection is reopened.

During the connection process, any server responses to subsequent

NetConnection.call,

NetStream.send, or SharedObject.send methods are queued until the server authenticates the

connection and

NetConnection.onStatus is invoked. The call or send methods are then

processed in the order received. Any pending updates to remote shared objects are also queued

until the connection is successful, at which point they are transmitted to the server.

Video and audio, however, are not queued during the connection process. Any video or audio

that is streaming from the server is ignored until the connection is successfully completed. For

example, confirm that the connection was successful before enabling a button that calls the

NetStream.publish method.
