browser refresh button repeats the previous request (assuming there was no ajax request in between) per my knowledge i don't know of a way to flag the refresh with any other attributes to create a special request. — DevZer0, Jun 19 '13 at 12:47
Why would you want to do this? It sounds like there is something else incorrectly structured in your code. — Paddy, Jun 19 '13 at 12:50
Why do you want to do that? It's not a common behaviour for a web application. — Alexander, Jun 19 '13 at 13:14

in c# use:

Session.Abandon();

This will clear all session and assign new session key and Session_OnEnd() event will also be fired.

Logic to check if page is refreshed

If you want to check the page is refreshed or not, then you can use cookies for that matter.

Store a cookie when page is visited first time. On refresh, check if your cookie exists or not.

see: Check if page gets reloaded or refreshed in Javascript

based on this you can apply clear session when your page is refreshed.

Here is code for reference:

$(document).ready(function() {
  if(document.cookie.indexOf('mycookie')==-1) {
    // this mean cookie doesn't exist and user visited first time
    document.cookie = 'mycookie=1';//set the cookie to check for next time
  }
  else {
    // cookie is not null i.e. page is refreshed, 
    //So, make an ajax call to handler and use Session.Abandon() on handler in c# code.
  }
});

Also, when browser will be closed, cookie will be automatically cleared.

I know how to abandon a session. I want to clear the session only on Browser refresh button... – Dylan Jun 19 '13 at 12:51
First check your page is refreshed or not by the help of cookies, if so, then use an ajax call to handler that clear session. – Sanjeev Rai Jun 19 '13 at 13:01
How would you know the Page is refreshed instead of visited for a second time? – Alexander Jun 19 '13 at 13:13
@Dynan, if cookie is not null then page is refreshed! See my edited answer. – Sanjeev Rai Jun 19 '13 at 13:24

//this will solve the postback part (button click). 
//The refresh you should handle with querystring params
protected void Page_Load(object sender, EventArgs e) 
{
  if(Page.IsPostBack)
     Session.Abandon();
}

Page.IsPostBack will be evaluated to false when refresh is done. This is used to know when postback is done, not to know if refresh is done. – Narendra Jun 19 '13 at 12:54
I know that. Did you read the comment in my code? – Thiago Custodio Jun 19 '13 at 14:09
