Question

which event is rised up in Internet Explorer (IE9) when the F5 key (refresh) is clicked? And how can I catch it with an Handler in my BHO?

Note:
I have created a BHO in C# for IE9. My class extend IObjectWithSite that allow me to add handlers through SetSite function.

public int SetSite(object site)
 {
   webBrowser = (SHDocVw.WebBrowser)site; 
   //events here...
 }

There is no direct method and it is hard to implement across different versions of IE. Although you can use combination of some events to achieve that. Be warned the following approaches are not fool proof.
