HTTP requests are messages sent by the client to initiate an action on the server, and they use [[HTTP Methods]]; alternatives include WebSockets and HTTP/2, which allow full-duplex communication and multiplexing, respectively. Django, a Python web framework, handles these requests on the server-side, whereas React.js, a JavaScript library, manages the client-side, making HTTP requests to fetch or send data and update the UI accordingly. Understanding and efficiently managing these requests and responses is crucial for web development as it ensures smooth communication between client and server, ultimately enhancing user experience and application performance. ![[Pasted image 20230824170548.png]]
