Create a login screen in Flash with text fields to accept a username and a
password. Write a function using the LoadVars Class and use the sendAndLoad()
method to send the username and password to a server side script (PHP, ASP, CF
and others). Your server side script then queries the database, checks the
values and prints true or false which value will be received by Flash (as a
string by the way) and based upon the result you have an action in your Flash
function that either forwards the user to the next frame or displays an error
message.
