A Redis based SessionStateStoreProvider written in C# using ServiceStack.Redis.

Harbour.RedisSessionStateStore

This is a Redis based SessionStateStoreProvider written in C# using ServiceStack.Redis.

Installation

1. You can either install using NuGet: PM> Install-Package Harbour.RedisSessionStateStore
2. Or build and install from source: msbuild .\build\build.proj

Usage

Configure your web.config to use the session state provider:

<system.web>
  <sessionState mode="Custom" customProvider="RedisSessionStateProvider">
    <providers>
      <clear />
      <add name="RedisSessionStateProvider" 
           type="Harbour.RedisSessionStateStore.RedisSessionStateStoreProvider" 
           host="localhost:6379" clientType="pooled" />
    </providers>
  </sessionState>
</system.web>

This configuration will use a PooledRedisClientManager and use the default host and port (localhost:6379). Alternatively you can use the host attribute to set a custom host/port. If you wish to change the client manager type to BasicRedisClientManager, you can set the clientType="basic".

If you require that a custom IClientsManager be configured (for example if you're using an IoC container or you wish to only have one IClientsManager for your whole application), you can do the following when the application starts:

private IRedisClientsManager clientManager;

protected void Application_Start()
{
    // Or use your IoC container to wire this up.
    this.clientManager = new PooledRedisClientManager("localhost:6379");
    RedisSessionStateStoreProvider.SetClientManager(this.clientManager);

    // Configure options on the provider.
    RedisSessionStateStoreProvider.SetOptions(new RedisSessionStateStoreOptions()
    {
        KeySeparator = ":",
        OnDistributedLockNotAcquired = sessionId =>
        {
            Console.WriteLine("Session \"{0}\" could not establish distributed lock. " +
                              "This most likely means you have to increase the " +
                              "DistributedLockAcquireSeconds/DistributedLockTimeoutSeconds.", sessionId);
        }
    });
}

protected void Application_End()
{
    this.clientManager.Dispose();
}

Changelog

v1.4.0

• Use the HttpContext.Session.Timeout instead of the timeout from the web.config so that the request can customize the session's timeout.

v1.3.0

• Use a distributed lock rather than the WATCH/UNWATCH pattern because it was causing issues.
• Add the ability to configure the provider with static SetOptions(options).

v1.2.0

• Always ensure UNWATCH is called.
• Retry a transaction once if it fails.

v1.1.0

• Add WATCH/UNWATCH pattern for transactions.

v1.0.0

• Initial release.
