[Net->Accept] is used with TCP listeners to accept an incoming connection. The tag returns a new [Net] object that represents the connection with the remote server that initiated the request. [Net->Accept] will wait forever for an incoming connection. [Net->Accept] can be used multiple times to accept requests from many different remote servers using the same listener.
In order to prepare a [Net] object as a listener the [Net->SetType] tag must be called with [Net_TypeTCP], the object must be bound to a port using [Net->Bind] and the object must be put into listening mode using [Net->Listen].
<?LassoScript
Variable: 'Listener' = (Net);
$Listener->(Bind: 8000);
$Listener->(Listen);
Variable: 'Connection' = $Listener->Accept;
...
$Connection->Close;
$Listener->Close;
?>
No Parameters Required.
To listen for incoming TCP connections:
Use the [Net] type and its member tags to establish a TCP listener. The following example listens on port 80 for incoming TCP traffic. The [Net->Accept] tag returns a new connection and the IP address of the local machine and the remote machine are reported.
[Variable: 'myListener' = (Net)]
[$myListener->(Bind: 80)]
[$myListener->(Listen)]
[Variable: 'myConnecton' = $myListener->(Accept)]
Local: [Output: $myConnection->(LocalAddress)]
Remote: [Output: $myConnection->(RemoteAddress)]
[Variable: 'Input' = $myConnection->(Read: 32768)]
...
[$myConnection->(Close)]
[$myListener->(Close)]
