What is the code sent to request information from a web application known as?

The code sent to request information from a web application is known as an HTTP Request. This terminology is rooted in the Hypertext Transfer Protocol (HTTP), which is the foundation of data communication on the World Wide Web. An HTTP Request consists of several components including the method (such as GET or POST), the URL, and headers that define the request's context.

When a client (like a web browser) wants to retrieve data or perform some action on a server, it sends an HTTP Request to the server. The server then processes this request and responds accordingly, typically with an HTTP Response that contains the requested information or an error message. Understanding the role of HTTP Requests is crucial for web development as it establishes how clients and servers communicate over the internet.

While other terms like "HTTP Query," "Web Request," and "Server Call" may be used in various contexts, they don't precisely capture the definition and standardized usage associated with the term "HTTP Request." Thus, recognizing the specific terminology and its application is key in understanding web communication.
