HTTP Request Methods

PUT method: uploads a new file (object) to the server and completely replaces a file that already exists at the specified URL.
GET method: sends data to the server by including user data in the URL field of the HTTP request message, following a '?', e.g., www.somesite.com/animalsearch?monkeys&banana.

HTTP Request Message Structure

An HTTP request message consists of a start-line, header section, and message body.

Types of HTTP Requests

POST method:
- Often includes a form with user input sent from the client to the server in the entity body of the HTTP request.
- Used to upload a new file (object) to the server.
HEAD method: requests only the headers that would be returned if the specified URL were requested with an HTTP GET method.
GET method:
- Can be used to request a specific resource from the server.
- Example of a minimal GET request: GET /fee/NewsDetails/142317/en HTTP/1.1 with the Host header set to www.menofia.edu.eg.
