Is there a way to capture if the person has clicked on the refresh button of the browser?
Is there a way to refresh a JSP which is covered by 5-7 frames(wrapper for the site. frameset) ?

Why not use the 'onUnLoad' method?
    <frameset .... onUnLoad='doSomeCk()'>
With this in your top level Frameset, you can do a check when the 
reload button his hit, or when the entire frameset is changed.
Make a decition in this method call and decide what to do.

The refresh-button triggers an event that is out of reach of js, so it 
is not possible to capture it by those means.
Generally all the buttons like "Back", "Forward", "Refresh" etc. are 
out of reach for js.
Sorry, but that's the way it is.
The only workaround that comes to my mind is to place a refresh-button 
inside the webpage (in the navigation-frame for instance) and have the 
user refresh the content by this button. Of course most users will 
still use the usual button, but at least you have an alternative.
