Explanation:
Main Differences Between Ajax GET and POST Requests
Ajax (Asynchronous JavaScript and XML) is a technique used to send and retrieve data from a server without refreshing the entire web page. The two main types of Ajax requests are GET and POST. GET requests are used to retrieve data from the server, while POST requests are used to send data to the server.
The main differences between GET and POST requests are:
Data Encoding: GET requests encode data in the URL, making it visible in the browser's address bar. POST requests send data in the message body, keeping it hidden from the user.
Data Length: GET requests have restrictions on the length of data that can be sent, while POST requests have no such limitations.
Caching: GET requests can be cached by the browser, while POST requests are not cached.
Ajax GET and POST requests are methods to send data to the server. The GET method sends data in the URL, which can be accessed via QUERY_STRING. However, the POST method sends data in HTTP message body which can be accessed using $_POST array.
Ajax is a tool used for exchanging data with a server and updating parts of a web page without reloading the whole page. Ajax GET and POST requests are two different techniques for sending data to the server. The GET method appends form-data to the URL in name/value pairs and is used to request data from a specified resource. The data sent by GET method can be accessed using QUERY_STRING environment variable. On the other hand, the POST method sends form-data as HTTP message body and requests for the resource to accept/store the data enclosed in the body of the request message. Data sent through POST method can be accessed using $_POST array. Hence, their main differences lie in how they send data and how that data can be accessed.
