Bypassing CloudFlare's time-out of 100 seconds

Question

I am attempting to AJAX-ify my reports in order to bypass the 100 seconds time-out that CloudFlare imposes on requests that run through its site.

Since cloudflare does not cache html or xhr, you can greycloud a subdomain but on the server use that as an alias. For example...

In CloudFlare dns:

• www 123.123.123.123 = orange (protected)
• ajax 123.123.123.123 = grey (dns only)

In your website control panel add ajax.mydomain.com as an alias.

Finally, in your code use the fqdn that hits your server bypassing cloudflare.

function ajaxReport() {
    var seconds = prompt("Please enter how many seconds you want the report to run", "5");
    $('#imgWaiting').show();
    $.post("//ajax.mydomain.com/post/post_ajaxReport.jsp",
  {
    theParam:seconds
  },function(data) {
    $('#imgWaiting').hide();
    window.location=data;
 });
}

This does expose your IP address. But there should be little to no performance penalty, depending on the content returned.
