In this topic, we will create a Web Server using Arduino and W5100 Ethernet module. However, this Web Server will not need a page refresh to update the data it shows, unlike the Web Server in the previous topic. We will give this feature to the Web Server using ” Asynchronous JavaScript and XML ” (AJAX). AJAX, “Javascript” and ” XMLHttpRequestIt is a structure that enables developing interactive Web applications with the server using In this way, the data displayed on the website can be updated without the need for a page refresh, or real-time communication can be provided between the website and the server. Take the Google search engine as an example. Without AJAX you would have to refresh the page every time google could suggest it to you. This would turn out to be an unusable situation.
