I would like to know if ASP.NET has something similar to session_id function from PHP.
I would like to do something like it using ASP.NET:
session_id($_GET['session_name']);
session_start();
if ($_SESSION['mydata'] != 'somepreviousvaluesetted') {
header("HTTP/1.0 404 Not Found");
exit;
}
The session object has a SessionID property, but it does not give you the ability to start a session; however, in global.asax, there is a Session_Start handler which fires when the session does start. The session starts when the user accesses the application.
