ClientSideSessionTimeout (nuget): This is to check timeout value and show a warning popup before timeout at client screen. You have to set session timeout value and warning time value in web.config and add js and css to the page just follow the 4 easy steps as described in a text file inside Instruction folder. This demo created in mvc razor but this same can be done in other web technologies. Multiple tab support is there, so if you are logged in and inactive in one tab and active in another tab then both the sessions will be active. Minimum requirement is js support.
