The code is flawless, however, it doesn't work (for you) because you
are unable to "find" the IFrame in your case.

I don't see why you have to do a FindControl. You can simply refer to
it using the ID. It will be of the type HtmlGenericControl :

frame1.Attributes["src"]

Is your IFrame in the master page?  Then you need to use Master and not "this".
For example I made a simple master page with a label and a menu.  To get to
those controls I use:

((Label)Master.FindControl("lblHeader")).Text = "Test";
((Menu)Master.FindControl("Menu1")).Items[0].ChildItems[0].Selected = true;

So maybe try:

HtmlControl frame4 = (HtmlControl)Master.FindControl("frame1");
