DynamoDBSessionStateStore is a custom session state provider that can be used inside of an ASP.NET application. Session state is saved inside a DynamoDB table that can be configured in the web.config. If the table does not exist the provider will create it during initialization with default read and write units set to 10 and 5 unless configured otherwise. If the table is created the application startup will block for about a minute while the table is being created. Example web.config entry setting up the session state provider.

CopyC#

<sessionState 
  mode="Custom" 
  customProvider="DynamoDBSessionStoreProvider"gt;
  <providers>
    <add name="DynamoDBSessionStoreProvider" 
         type="Amazon.SessionProvider.DynamoDBSessionStateStore"
         AWSAccessKey="YOUR_ACCESS_KEY"
         AWSSecretKey="YOUR_SECRET_KEY"
         Region="us-east-1"
         Table="ASP.NET_SessionState"
         />
  </providers>
</sessionState>

The schema for the table used to store session requires a string hash key with no range key. The provider will look up the name of the hash key during initialization so any name can be given for the hash key.

Below is a list of configuration attributes that can specified in the provider element in the web.config.
