What is ASP.NET SQL Server Session?

ASP.NET SQL Server SessionThe period that a user takes to interact with an Application in the web is referred to as a session. Session state is the feature, which is intrinsic, and is used by ASP developers who want to keep data for special user sessions for different purposes. Session state is simply a memory which comes in form of a dictionary or may be a hash table for instance key-value pairs which will be enabled and later read to determine the duration of the user’s session.

Why SQL?

When running many web servers, for a single site, the session state for the default, InProc becomes useless as the site owner cannot be sure that every page request is directed to the same server. Therefore, it becomes inevitable to acquire a central state store that will be accessed by each web server.

SQL Server gives a centralized session state storage inside a Web farm. SQL also offers transactional capabilities that give reliability to a number of database systems that are related. Thus, SQL Server can be used to save a session.Why SQLHowever, the process above is not as efficient as StateServer and InProc mode. This is because information has to be stored in a different server and in a different process. Still, the process comes handy as compared to using aspnet_state service. This will depend on the database configurations and the workload. The session state that has been saved on SQL database persist even through web server reboots and restarts. You should store the session state for reliability purposes. This is done on SQL cluster for a web farm

There are three distinct modes that can be used to store the information for each session. These are StateServer, SQLServer and InProc. There are both benefits and disadvantages for using each of the methods above. InProc offers the fastest performance for the simple reason that the session storage is located in the IIS Worker Process. The disadvantage is that the session may be lost in the event that the Worker Process is recycled.

SQL Server is slower than InProc, estimated to be 15-20% slower, but keeps the session data intact even after recycling the Worker Process. The statement management mode that you choose will depend on the appropriateness for the web application. For instance, you may not want to lose any session data and to this end you go for the SQL Server in place of the InProc.
