A WebRequest is a programming object used to send requests to a web server and receive responses. It is commonly utilized in applications that need to interact with web resources, such as APIs or web pages. By using a WebRequest, developers can specify the type of request (like GET or POST), set headers, and manage data sent to or received from the server. When a WebRequest is made, it connects to the specified URL and retrieves the requested information. This process is essential for applications that rely on real-time data from the internet, enabling functionalities like fetching user data, submitting forms, or downloading files.
