Web Transaction Processing

So far, our application enables the user to view information about films and show times. Now, we are ready to take the next step: adding transaction processing capabilities, so that user can purchase tickets.

Specifically, in this part of the tutorial we're going to:

• Create a server-side method and call it from a Web page;

• Define a page programmatically, using server-side code, rather than a CSP file;

• Learn about session management and how to detect and clean up when the user abandons a transaction; and

• Modify the contents of a Web page, in response to a browser event, without retransmitting the entire page.
