If this flag is set to false and the table doesn’t exist, an exception will be thrown.Īs a security best practice, we recommend that you run your applications with the credentials of an AWS Identity and Access Management (IAM) user. CreateIfNotExist controls whether the table will be auto created if it doesn’t exist. CreateIfNotExist – optional boolean attribute.The write capacity units if the table is not yet created. WriteCapacityUnits – optional int attribute.The read capacity units if the table is not yet created. ReadCapacityUnits – optional int attribute.The name of the table used to store session data. Application is used to partition the session data in the table so it can be used for more than one application. Application – optional string attribute.This can be set either in the provider definition or in the appSettings section. Once the application is configured and the table is created, sessions can be used like any other session provider.īelow are the configuration attributes that can be used in the XML provider definition in your web.config file: See the web.config options below for how to configure the Amazon DynamoDB table. If you don’t create the table before starting the application it can be created automatically during initial startup. See the DynamoDB pricing page for additional information. If you are eligible for the AWS Free Usage Tier, you can consume up to 100 MB of DynamoDB storage, 5 units of write capacity, and 10 units of read capacity at no charge for one year. We recommend that you create this table before first running your application, with a string hash key, no range key and the desired values for ReadCapacityUnits and WriteCapacityUnits. When your application starts, it looks for a DynamoDB table called ASP.NET_SessionState. NET and are setting the access and secret keys in the appSettings section of your application’s web.config file, you can leave the access and secret keys blank in the sessionState element the SDK will then discover the keys at runtime. This is the account that will be used to communicate with Amazon DynamoDB to store and retrieve the session state. You need to provide access and secret keys for a valid AWS account where indicated. Next, edit your application’s web.config filein the system.web element, replace or add the sessionState node with the following XML fragment: NET installer and available through NuGet. To configure an ASP.NET application to use Amazon DynamoDB as the session state server, you need to add references to AWSSDK.dll and which are both part of the AWS SDK for. We also added the AmazonDynamoDBSessionProviderSample sample which demonstrates using Amazon DynamoDB as a session state provider. NET, we added the which contains an ASP.NET session state provider. The only administrative decision to make is how much you want to scale. Of course, this approach has certain drawbacks: you must administer another machine, the session state server is a single point of failure, and the session state server can be a performance bottleneck.Īmazon DynamoDB, a new NoSQL database store from Amazon Web Services (AWS), is designed to address these drawbacks. The common solution to sharing session state over multiple web servers is to set up a dedicated session state server with SQL Server. Unfortunately, this approach doesn’t scale very well once your application grows beyond a single web server, the session state must be shared between servers. When developing a new ASP.NET application, a common approach is to store session data in memory. Norm has put together a post to show you how to track the session state of an ASP.NET application uusing Amazon DynamoDB. Session variables are single-user global data stored on the web server, meaning by default a session state variable is stored in the web server memory and is available across all pages but it will be for a single session.Today we have guest post from Norm Johanson, a Software Developer on our Developer Resources team. public partial class MysessionPage : .Page.After navigating to the page mysessionpage.aspx and retrieving value from session.protected void Button2_Click( object sender, EventArgs e).TextBox1.Text = SessionCounter.ToString().
