this weired , inefficient way making website. never implement on production server.

1 step - encapsulate iframes in seperate update panel.

2 step - add timer control in updatepanel minimum refresh rate comformable with.

3 step. logic smthing this, when ever link clicked menu iframe set session variable required parameter session["togo"] = "blabla.aspx"

4 step in timer tick event check session if found reload iframe value specified. set session["togo"] null.
