I'm having a web application which is using PHP/MySQL pair. Now i like to replace only the AJAX requests to node.js to reduce the latency to less than 1 second. So when i googled about this, i came to know about node.js as the efficient way to implement this. But it is not possible for me to replace the entire PHP system to node.js, so i'm in the idea of only changing the AJAX requests to node (The current system is in JQuery/PHP). So i like to know about the possibility and some guidance of changing only the AJAX requests to node.js. Any idea or directions on this would be greatly appreciated.
