How can we distinguish between browser close events and
browser refresh events (using icon and F5 key)?

Solution 1

Short answer, you can't as neither one is a single defined 'event'.
For example the onUnload event will be raised when the browser closes BUT it is also called when you navigate away from the page, so not suitable.

Here is a solution for that
if there is a postback due to an action on the control, document.getElementByID('__EVENTTARGET') will not be null. So using this hidden field you can know wich control fired the postback in the page.
 
Else if this a normal refresh then this value will be null always.
 
So you can check this value in the CodeBehind to know.
 
Hope this will help you
