I would like to refresh an iframe on my website at a given interval. I have some code below. It is not working when I use the url in the src.  However, if I replace the iframe src with an image file vs a url, it works fine. Any one  know why?

<head>
    <title>Untitled Page</title>
    <SCRIPT LANGUAGE="JavaScript">
<!--

var secs
var timerID = null
var timerRunning = false
var delay = 1000

function InitializeTimer()
{
    // Set the length of the timer, in seconds
    secs = 25
    StopTheClock()
    StartTheTimer()
}

function StopTheClock()
{
    if(timerRunning)
        clearTimeout(timerID)
    timerRunning = false
}

function StartTheTimer()
{
    if (secs==0)
    {
        StopTheClock()
        self.status = ""
        // Here's where you put something useful that's
        // supposed to happen after the alotted time.
        // For example, you could display a message:
       
        refresh();
        InitializeTimer();
    }
    else
    {
        self.status = secs
        secs = secs - 1
        timerRunning = true
        timerID = self.setTimeout("StartTheTimer()", delay)
    }
}
