会话状态

有三种处理模型:

 

1-默认是InProc

<sessionState ... mode="InProc" />

2-StateServer

Start Aspnet_state.exe. You can start it manually (from the command line) by executing the following command:

net start aspnet_state

<configuration>
  <system.web>
    <sessionState
      mode="StateServer"
      stateConnectionString="tcpip=localhost:42424"
    />
  </system.web>
</configuration>
<configuration>
  <system.web>
    <sessionState
      mode="StateServer"
      stateConnectionString="tcpip=192.168.1.2:42424"
    />
  </system.web>
</configuration>
    
    

• Add the desired port number to the registry at HKEY_LOCAL_ MACHINE/System/CurrentControlSet/Services/aspnet_state/ Parameters/Port.

• Replace 42424 with the new port number in stateConnectionString.

    sql Server Session State
   
   
   
   

    
    

Create the database that holds the session state. The .NET Framework SDK provides a script that creates the database for you; it’s called InstallsqlState.sql. To run it,open a command prompt window and type the following command:
 
     
 
      
osql -S localhost -U sa -P -i installsqlstate.sql
 
     
 
This command creates a sql Server database named ASPState on the host machine and adds to it all the tables,stored procedures,and other infrastructure that ASP.NET uses to access the database,as shown in figure 9-11.
 

    
    
 
Add a mode=“sqlServer” attribute and a sqlConnectionString attribute to the sessionState element in Machine.config or a local Web.config file. The latter of these two attributes provides the @R_308_4045@ion ASP.NET needs to connect to the database
 

   
   

<configuration>
  <system.web>
    <sessionState
      mode="sqlServer"
      sqlConnectionString="server=localhost;uid=sa;pwd="
    />
  </system.web>
</configuration>

后两种会话状态需要对象的串行化.利用..net平台强大的串行化机制.

<sessionState timeout="60" />

Session.Abandon ();

<%@ Page EnableSessionState="false" %>

<sessionState mode="Off" />
