FAQ

Q: Which application layer protocol uses message types such as GET, PUT, and POST?

A: The application layer protocol that uses message types such as GET, PUT, and POST is the Hypertext Transfer Protocol (HTTP). These methods correspond to various operations that can be performed on resources identified by URLs.

Q: What is the purpose of the GET method in HTTP?

A: The GET method is used to request data from a specified resource. When a client sends a GET request to a server, it is asking the server to send back the resource’s data. GET requests are idempotent, meaning that multiple identical requests will yield the same result without causing any changes to the server state.

Q: How does the PUT method differ from the POST method in HTTP?

A: The PUT method is used to update a resource or create a new resource at a specified URI, with the request body containing the updated or new data. If the resource already exists, PUT replaces it; if it does not, a new one is created. On the other hand, the POST method is generally used to submit data to a server to create a new resource or trigger a specific action, and it does not guarantee idempotency, meaning submitting the same POST request multiple times may result in different outcomes.

Q: Are GET requests secure for transmitting sensitive information?

A: No, GET requests are not secure for transmitting sensitive information. Since GET requests append data to the URL, any sensitive information can be visible in browser history and server logs. For secure transmission of sensitive information, POST requests should be used, ideally over HTTPS, to ensure data is encrypted between the client and server.

Q: Can the HTTP methods GET and POST be cached?

A: GET requests can be cached by default since they are used to retrieve data without side effects. However, caching can be controlled using HTTP headers. POST requests, however, are generally not cached because they change the server state and may produce different results each time they are executed; however, caching behavior can also be influenced by appropriate caching directives in the headers.
