Disable Browser Back and Forward Button after logout

With the use of following code you can restrict user to go back or forward after Logout. Just write this code on your masterpage load event

Response.AppendHeader("Cache-Control", "no-store")

You can also Remove browser Cache Memory with the use of following code

//code for no cache in browser

Response.ExpiresAbsolute=DateTime.Now.AddDays(-1d);

Response.Expires =-1500;

Response.CacheControl = "no-cache";

You can only use

Response.CacheControl = "no-cache";

But it is a good prectice to expire all cache.
