If you want to disable session state for only a particular page of an application, set the EnableSessionState page directive to False. You can also set the EnableSessionState page directive to ReadOnly to provide read-only access to session variables. The following code sample shows how to disable session state for a single page:

Configuring Cookieless Session State
By default, session state uses cookies to track user sessions. This is the best choice for the vast majority of applications. Almost all Web browsers support cookies, and those that don t are typically clients you don t want to track session data for, such as search engines or other robots. However, you can enable a cookieless session state to have ASP.NET track sessions using a query string in the URL. The session ID is embedded in the URL after the slash that follows the application name and before any remaining file or virtual direc tory identifier. For example, the following URL has been modified by ASP.NET to include the unique session ID lit3py55t21z5v55vlm25s55:
http://www.example.com/s(lit3py55t21z5v55vlm25s55)/orderform.aspx
The following example shows a Web.config file that configures an ASP.NET applica tion to use cookieless session identifiers.
<configuration> <system.web> <sessionState cookieless="true" regenerateExpiredSessionId="true" /> </system.web> </configuration>
Responding to Session Events
ASP.NET provides two events that help you manage user sessions:
Session_Start
Raised when a new session begins. This is the perfect place to ini tialize session variables. Raised when a session is abandoned or expires. Use this to free persession resources.
Session_End
Lesson 2: Using Server-Side State Management
To implement these events, add the Global.asax file to your project and write code in the appropriate event handler, as discussed in the section Responding to Application Events, earlier in this lesson.
Choosing a Session State Mode
ASP.NET session state supports several different storage options for session data:
InProc
Stores session state in memory on the Web server. This is the default, and it offers much better performance than using the ASP.NET state service or storing state information in a database server. InProc is fine for simple applica tions, but robust applications that use multiple Web servers or must persist ses sion data between application restarts should use StateServer or SQLServer.
StateServer
Stores session state in a service called the ASP.NET State Service. This ensures that session state is preserved if the Web application is restarted and also makes session state available to multiple Web servers in a Web farm. ASP.NET State Service is included with any computer set up to run ASP.NET Web applications; however, the service is set up to start manually by default. Therefore, when configuring the ASP.NET State Service, you must set the startup type to Automatic. Stores session state in a SQL Server database. This ensures that ses sion state is preserved if the Web application is restarted and also makes session state available to multiple Web servers in a Web farm. On the same hardware, the ASP.NET State Service outperforms SQLServer. However, a SQL Server data base offers more robust data integrity and reporting capabilities. Enables you to specify a custom storage provider. You also need to implement the custom storage provider.
SQLServer
Custom
Off
Disables session state. You should disable session state if you are not using it to improve performance.
Configuring Session State Modes
You can specify which mode you want ASP.NET session state to use by assigning Ses sionStateMode enumeration values to the mode attribute of the sessionState element in your application s Web.config file. Modes other than InProc and Off require additional parameters, such as connection-string values. You can examine the currently selected session state by accessing the value of the System.Web.SessionState.HttpSessionState.Mode property.

ASP.NET State Management
For example, the following settings in a Web.config file cause the session state to be stored in a SQL server database identified by the specified connection string:
<configuration> <system.web> <sessionState mode="SQLServer" cookieless="true " regenerateExpiredSessionId="true " timeout="30" sqlConnectionString="Data Source=MySqlServer;Integrated Security=SSPI;" stateNetworkTimeout="30"/> </system.web> </configuration>
While you can configure session state for your application, that is typically the respon sibility of systems administrators. For example, a systems administrator might ini tially configure your Web application on a single server using the InProc mode. Later, if the server gets too busy or requires redundancy, the systems administrator adds a second Web server, configures the ASP.NET state service on a server, and modifies the Web.config file to use the StateServer mode. Fortunately, the session state mode is transparent to your application, so you won t need to change your code. Besides con figuring the Web.config file, you don t need to change how your application deals with session states to support different modes.
