If I'm not wrong, you're trying to share the session across multiple ASP.NET applications.

Here's how you do it...

1) Use SQL Server for storing session state.

2) Tweak "TempGetAppID" in the session database so that it returns session values for multiple applications - refer to the below link to achieve this.

Hope this helps.

For SQl Server

For State Server

<sessionState mode="StateServer" stateConnectionString="tcpip=127.0.0.1:55455" sqlConnectionString="data source=127.0.0.1;user id=sa;password='' cookieless="false" timeout="20"/>

For SQL Server

<sessionState mode = "SqlServer" stateConnectionString="tcpip=127.0.0.1:45565"

sqlConnectionString="data source="SERVERNAME;user id=sa;password='' cookiesless="false" timeout="20"/>

Dear bro...

Plz let me know. My project have using many web application. So, do I need to write this SessionState any web.config file from every application and were can I write this in web.config.

Hello,

Session in ASP.net can be stored in 3 ways.
1. Inproc
2. State Server
3. SqlServer

The InProc mode of Session State management is the fastest among all of the storage modes available and stores the Session data in the ASP.NET worker process.
Performance will be effected if the amount of data stored in the session is large. Basically the session is stored in the memory space of an application
domain and is volatile.So if asp.net worker process i.e. aspnet_wp.exe restarts then the session state will be lost.
The Session State here entirely depends on the lifetime of the application domain that it runs on. Note that the Session_End event which is fired internally by the web server is supported only in InProc mode. Note that even if the Session State is set to read only using the EnableSessionState attribute, in the InProc mode one can still modify the session. The Session_OnEnd event is invoked by the runtime environment when we make a call to the Session.Abandon() method or when the user's session times out. Further, any change made in the settings in the web.config file unloads the application domain and the Session State too.

The StateServer mode uses a stand-alone Microsoft Windows service that is independent of IIS and can run on a separate server.
In this case the session state is serialized and stored in memory in a separate process that is managed by the aspnet_state.exe file.
This has got some performance drawbacks due to the overhead involved in serialization and de-serialization of objects.
The main primary advantage of storing the Session State in a State Server is that it is not in the same process as the ASP.NET and a crash of ASP.NET
would in no way destroy the session data. Secondly, this mode of Session State storage enables to share the information across a web garden or a web farm.

Rememeber that this mode is slow compared to the InProc mode as it is stored in an external process.

The SQLServer mode of Session State management is a reliable, secure and centralized storage of a session state
In this the Session data is serialized and stored in a database table in the SQL Server database.
It can typically be used in the web farms.

It has performance bottlenecks as in the State Server mode of Session State management due to the overhead involved in serialization and de-serialization
of the objects that are stored and retrieved to and from the Session.
SQL Server is more secure than the InProc or the State server modes of Session State storages as the data can be secured easily by
configuring the SQL Server security.

I hope this will helps you out..

Use Out Process and save your session in Sql server it will easy to manage

Using eighter SQL Server Session State or State Servers instead of the default InProc mode has the benefit of making your site more scalable and reliable by storing session information on a SQL Server database or on another machine on the web farm. So in both scenarios the web server will be less busy handling session information and will have more time to service requests. On the other hand, the InProc mode is the fastest mode because it keeps all the information on the web server's memory. You can also take a look at the following greate links for more information on choosing the right mode and configuring OutProc session state management:

For SQl Server

For State Server

The attributes are self explanatory but I will go over them.

mode: This can be StateServer or SqlServer. Since we are using StateServer we set the mode to StateServer.

stateConnectionString: connectionString that is used to locate the State Service.

sqlConnectionString: The connection String of the sql server database.

cookieless: Cookieless equal to false means that we will be using cookies to store the session on the client side.

For SQL Server

<sessionState mode = "SqlServer" stateConnectionString="tcpip=127.0.0.1:45565"

sqlConnectionString="data source="SERVERNAME;user id=sa;password='' cookiesless="false" timeout="20"/>
