Prior Art Detail
Summary / Description
| Summary / Description | ColdFusion developers rely on session state management and the SESSION scope extensively. But as applications grow in complexity, so do the number of SESSION variables, and the risk of overwriting or misusing them. It need not be that way; with a little work (and ColdFusion Components), SESSION use can be clean, simple, and highly organized. |

Excerpt
Excerpt ...The Web is stateless. Or put in terms that actually mean something, every request on the Web stands on its own two feet. The data received by a form submission, for example, is only available in the receiving page and not to subsequent requests. Or, user credentials specified at login are not kept until logout. And similarly, items put in a shopping cart won't still be in the cart at checkout time.
But wait a minute, those statements can't be true, can they? After all, we've all put items in shopping carts and then checked out, and we've all logged in to sites that remembered us until logout, haven't we? If the Web is stateless, how is that data maintained? That's the job of session state management, a mechanism that creates the illusion of state in a stateless world.
Data to be maintained between requests is stored on the server, along with an id that designates the client that the data belongs to. That id is sent back and forth with each and every request, so that the server can associate the maintained data and give the illusion of persistent data. In ColdFusion all this is accomplished using SESSION variables. Developers simply refer to variables like #SESSION.Firstname# and ColdFusion takes care of all the details (setting and receiving session identifiers, maintaining the SESSION data, and ensuring that the correct data is used when referring to variables with the SESSION scope).
...So you need to track session information, great. The first thing you do is set SESSIONMANAGEMNT="yes" in your <CFAPPLICATION> tag (which makes a lot of sense; after all, you can't use the SESSION scope without having first instructed ColdFusion to enable that functionality. Once enabled you are free to save any data within SESSION. For example, a simple variable: |
