VMware GemFire .NET Client - Session State

This is a sample code that stores a session state for an ASP.NET app (basically .NET Web App). It’s a command line simple program that connects to a region using cache factory object and does not involve any dependency on Java.

Before you continue, you need to follow these steps for SessionStateProvider sample works:

• In your Web.Config file, add below section under <system.web> section. The timeout value can be changed as needed:

   <!--GemFire SessionStateProvider-->
<sessionState mode="Custom" cookieless="false" timeout="20" customProvider="GemFireSessionProvider">
 <providers>
   <add name="GemFireSessionProvider" type="Pivotal.GemFire.Session.SessionStateStore" region="sessionStateRegion"/>
 </providers>
</sessionState>

• In Global.asax.cs code-behind file, you will need add a class called BasicAuthInitialize that implements the Apache.Geode.Client.IAuthInitialize interface. It can also be declared outside of the Global.asax.cs file, in its own class file (for example: BasicAuthInitialize.cs).

public class BasicAuthInitialize : IAuthInitialize
{
   private string _username;
   private string _password;
   
   public BasicAuthInitialize(string username, string password)
   {
       _username = username;
       _password = password;
   }
   
   public void Close()
   {
   }
   
   public Properties<string, object> GetCredentials(Properties<string, string> props, string server)
   {
       var credentials = new Properties<string, object>();
       credentials.Insert("security-username", _username);
       credentials.Insert("security-password", _password);
       return credentials;
   }
}

Please refer to the .NET Framework Native Client docs for more details.

• In Global.asax.cs file and under Application_Start() event, add the line that initializes the instance of BasicAuthInitializeClass class using its constructor that accepts the credentials.
• Make sure you have geode.properties and cache.xml files defined that contain the necessary information to connect to the GemFire cluster and client side properties. Please refer to this article for more details.
