ASP.Net JWT Token based SessionState Provider
The ASP.Net JWT Token based SessionState provider is a drop-in replacement for ASP.Net's default session state providers (in-proc, Asp.Net State Server, SQL Server) that is 100% stateless and requires no backend storage service.
This component was developed to totally remove the traditional session state bottleneck scaling issues on a +100,000K concurrent users corporate ASP.Net project.
- Drop-in replacement, no changes to your code are needed
- Scale better than any other centralized store, as no session storage backend is needed.
- Faster than any other session storage, as no data needs to be retrieved from any session storage
- Consumes no server resources for session storage
- Default non-blocking implementation: concurrent request won't block each other and hold a lock on the session
- Horizontally scale your application: because the session data travels with the request itself you can have multiple web heads without worrying about session sharing.
How does it work:
- Session data is embedded inside a JWT and sent to the client through a Cookie
- The server decodes the incoming cookie on every request to populate the session data.
- The server only sends new cookies to the client when the session data changes, or every couple of minutes in order to implement sliding session expiration.
- Sessions are not tracked anywhere on the server. You cannot invalidate a specific user session.
- By default, the contents of the JWT are not encrypted. Although it is difficult to reverse engineer the session contents (they are not stored as JSON data but as a direct object memory serialization), this is doable with some effort if you know how this provider works.
- We have an offering of an ecrypted JWT version of the service where the session contents are fully encrypted, but that comes at the cost of a bigger JWT token size, so you have more limits on to how much content you can store in the session before you reach HTTP header limits for your server.
How to deploy:
Add these settings to your web.config and you are ready to go:
<add name="Session" type="System.Web.SessionState.SessionStateModule" preCondition="integratedMode"/>
<sessionState timeout="10" cookieless="false" regenerateExpiredSessionId="true" mode="Custom" customProvider="TokenAsyncSessionStateProvider">
<add name="TokenAsyncSessionStateProvider" type="DrupalOnWindows.Session.TokenAsyncSessionStateProvider"/>
