That is usually all that you need to do     Are you sure that after 20 minutes  the reason that the session is being lost is from being idle though     There are many reasons as to why the session might be cleared  You can enable event logging for IIS and can then use the event viewer to see reasons why the session was cleared   you might find that it is for other reasons perhaps   You can also read the documentation for event messages and the associated table of events

You can find the setting here in IIS     It can be found at the server level  web site level  or app level under  ASP    I think you can set it at the web config level here  Please confirm this for yourself    lt configuration gt      lt system web gt          lt  -- Session Timeout in Minutes  Also in Global asax  -- gt          lt sessionState timeout  1440   gt       lt  system web gt   lt  configuration gt

Are you using Forms authentication   Forms authentication uses it own value for timeout  30 min  by default   A forms authentication timeout will send the user to the login page with the session still active  This may look like the behavior your app gives when session times out making it easy to confuse one with the other    lt system web gt       lt authentication mode  Forms  gt             lt forms timeout  50   gt       lt  authentication gt        lt sessionState timeout  60     gt   lt  system web gt    Setting the forms timeout to something less than the session timeout can give the user a window in which to log back in without losing any session data

Do you have anything in machine config that might be taking effect   Setting the session timeout in web config should override any settings in IIS or machine config  however  if you have a web config file somewhere in a subfolder in your application  that setting will override the one in the root of your application   Also  if I remember correctly  the timeout in IIS only affects  asp pages  not  aspx   Are you sure your session code in web config is correct   It should look something like     lt sessionState     mode  InProc      stateConnectionString  tcpip 127 0 0 1 42424      stateNetworkTimeout  60      sqlConnectionString  data source 127 0 0 1 Integrated Security SSPI      cookieless  false      timeout  60    gt

Since ASP Net core 1 0  vNext or whatever name is used for it  sessions are implemented differently  I changed the session timeout value in Startup cs  void ConfigureServices using   services AddSession options   gt  options IdleTimeout   TimeSpan FromSeconds 42      Or if you want to use the appsettings json file  you can do something like      Appsettings json  SessionOptions          IdleTimeout    00 30 00        Startup cs services AddSession options   gt  options IdleTimeout   TimeSpan Parse Config GetSection  SessionOptions    IdleTimeout
