title: How "Session_Start" in Global.Asax works ?. MVC
body: <p>I'am trying uderstand how "Session_Start" in Global.Asax works. Let's say I've got few pages on my website. For example: I'am entering on "Page A", then function "Session_Start" is firing. Then I'am going to "Page B", and what than ?. Function will firing again, or not ?. I'am trying to write code which will check that cookie "User" exist, and if exist, code will return Session["userName"] variable, but I'am not sure is "Session_Start" good place for that..  </p>
