ScaleOut StateServer’s session provider will automatically register for expiration events in order to fire a web application’s Session_End event in Global.asax. To prevent this registration and stop events from being delivered to Session_End, add the setting soss_RegisterForEvents with the value False to the application’s web.config file, as follows:
<configuration> <appSettings> <add key="soss_RegisterForEvents" value="False"/> </appSettings> ... </configuration>
