In Flash Lite applications connecting to Internet, it is useful to check the network status, while making the connection.

• If connection is being established or not
• If connection failed Network error
• If there is DNS Failure
• If no HTTP request has been made

In Flash Lite 1.1 GetNetworkRequestStatus command returns a value indicating the current status of the most recent HTTP request. It can be any of the following values.

• -1: The command is not supported.

• 0: There is a pending request, a network connection has been established, the server's host name has been resolved, and a connection to the server has been made.

• 1: There is a pending request, and a network connection is being established.

• 2: There is a pending request, but a network connection has not yet been established.

• 3: There is a pending request, a network connection has been established, and the server's host name is being resolved.

• 4: The request failed because of a network error.

• 5: The request failed because of a failure in connecting to the server.

• 6: The server has returned an HTTP error.

• 7: The request failed because of a failure in accessing the DNS server or in resolving the server name.

• 8: The request has been successfully fulfilled.

• 9: The request failed because of a timeout.

• 10: The request has not yet been made.

Example

You want to show loading with animation and some time count.

• Add this ActionScript code in the first frame

/:timerCount = "30";
/:requeststatus = fscommand2("GetNetworkRequestStatus");

• Type loading text with animated movie clip
• Load variable HTTP path.

loadVariables("http://www.google.co.in", "", "GET");

• Check the request of HTTP status

if (/:timerCount>=0) {
	play();
}

As GetNetworkRequestStatus returns 12 status values, you have to use switch statement to update a text with the current status in final_status.

switch (/:requeststatus) {
	case -1 :
		/:final_status = "Request status not supported" add "\n";
		break;
	case 0 :
		/:final_status = "Connection to server has been made" add "\n";
		break;
	case 1 :
		/:final_status = "Connection is being established" add "\n";
		break;
	case 2 :
		/:final_status = "Pending request, contacting network" add "\n";
		break;
	case 3 :
		/:final_status = "Pending request, resolving domain" "\n";
		break;
	case 4 :
		/:final_status = "Failed, network error" add "\n";
		break;
	case 5 :
		/:final_status = "Failed, couldn't reach server" add "\n";
		break;
	case 6 :
		/:final_status = "HTTP error" add "\n";
		break;
	case 7 :
		/:final_status = "DNS failure" add "\n";
		break;
	case 8 :
		/:final_status = "Request has been fulfilled" add "\n";
		break;
	case 9 :
		/:final_status = "Request timed out" add "\n";
		break;
	case 10 :
		/:final_status = "No HTTP request has been made" add "\n";
		break;
		gotoAndStop("error");
}
