it is considerate of you to put effort for this kind of user friendliness. However there is no client side js that can do this for you. However if the server you are linking to is one you have access to you could use a little ingenuity and give visual cues on wether or not the site is active.
Try putting a green image (1px by 1px) on the server you are linking to. name this image the name you want. Do a setTimeout to check if the image is complete after three seconds or so. if the image is not complete set the image src to red.
here is a quick code example that I never tested :
<img src="
name=another height=10 width=10>
<script>
function checkServerStatus()
{
if (!document.another.complete) // if it is not available
{
document.another.src = "red.png" // resides on your server
}
}
setTimeout("checkServerStatus()", 3000)
</script>
I didn't test this but I believe you could use similar tests with hidden image or image objects having for src an HTML page. This could make it even more interesting
Hope it helps. Gary "
