The HttpRequest class reads a request from a client socket, parses the method, URL, version, and headers, and stores them in variables. It also checks if the method is GET and handles any errors that may occur during the reading process. The HttpResponse class reads a response from a server, parses the status line, headers, and body, and stores them in variables. It also handles errors that may occur during the reading process. The classes provide methods to get the host, port, URL, and status of the request/response.
