Need help to set up a few files. I want to use a php script to detect server status, and javascript to automatically redirect to a server status page [on another server obviously] (only if the server is down)
immediately rather than get a 404 error.
I have a php script to detect server status and I can build a 'server down page' to redirect to, but im lost on the javascript! please help?
I image something like..
<script src="where the php script is"></script>
<script>
If ?server down,
redirect to src="where the 'server down page' is
?
</script>the php script
