HTTP Requests are messages sent by a client to a server asking for a resource on the web. These requests follow the Hypertext Transfer Protocol (HTTP) and can be of various types, such as GET (to retrieve data), POST (to send data), PUT (to update data), DELETE (to remove data), and more. Each request consists of a request line, headers, and an optional body. HTTP requests are fundamental to web scraping, as they enable the retrieval of web pages and data from servers. Understanding HTTP requests and responses is crucial for effectively navigating and extracting information from the web.
