CHAPTER 14• AUTHENTICATING YOUR USERSwww.it-ebooks.infoAuthenticating Against a MySQL DatabaseBecause Auth_HTTP subclasses the Auth package, it inherits all of Auth‘s capabilities. Because Authsubclasses the DB package, Auth_HTTP can take advantage of this popular database abstraction layer tostore authentication information in a database table. To store the information, this example uses a tableidentical to one used earlier in this chapter:CREATE TABLE logins (id INTEGER UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,username VARCHAR(255) NOT NULL,pswd CHAR(32) NOT NULL);Next, you need to create a script that invokes Auth_HTTP, telling it to refer to a MySQL database.
