I have a JavaScript function with two different URLs. The first URL is the default URL and the JavaScript jumps to it, but if the first URL does not exist, the JavaScript must jump to the second one. I need a function that checks if the first URL exist and depending the result of this function, jump to the first or the second URL.

However if you can put an image on the 1st server, you can try this:

<IMG SRC="http://www.server1.com/testimage.gif"
onLoad="window.location='http://www.server1.com/'"
onError="window.location='http://www.server2.com/'">
