Description

Event handler; invoked on the server side when NetConnection.connect is called from the

client side and a client attempts to connect to an application instance. You can define a function

for the

application.onConnect event handler. If you don’t define a function, connections are

accepted by default. If the server accepts the new connection, the

application.clients object

is updated.

You can use the

application.onConnect event in server-side scripts to perform authentication.

All the information required for authentication should be sent to the server by the client as

parameters (

p1 ..., pN) that you define. In addition to authentication, the script can set the access

rights to all server-side objects that this client can modify by setting the

Client.readAccess and

Client.writeAccess properties.

If there are several simultaneous connection requests for an application, the server serializes the

requests so there is only one

application.onConnect handler executing at a time. It is a good

idea to write code for the

application.onConnect function that executes quickly to prevent a

long connect time for clients.

Example

This example verifies that the user has sent the password “XXXX”. If the password is sent, the

user’s access rights are modified and the user can complete the connection. In this case, the user

can create or write to streams and shared objects in the user’s own directory and can read or view

any shared object or stream in this application instance.

// This code should be placed in the global scope

application.onConnect = function (newClient, userName, password){

// Do all the application-specific connect logic

if (password == "XXXX"){

newClient.writeAccess = "/" + userName;

this.acceptConnection(newClient);

}

var err = new Object();

err.message = "Invalid password";

this.rejectConnection(newClient, err);

};

If the password is incorrect, the user is rejected and an information object with a message

property set to “Invalid password” is returned to the client side. The object is assigned to

infoObject.application. To access the message property, use the following code on the client

side:

ClientCom.onStatus = function (info){

trace(info.application.message);

// it will print "Invalid password"

// in the Output window on the client side

};
