Questão
Which HTTP response status code should a web server (or web application) send to inform the client that a resource was moved to a new location? (1)
Responda
  • The HTTP status code 100 to instruct the client that further requests are required to complete the request

  • The HTTP status code 301 if the resource was moved permanently, or 302 if the resource was only moved temporarily
  • The HTTP status code 404 as the original resource was not found
  • The HTTP status code 504 as the resource has been changed on the server which means that it’s a server error

Questão
What is the main difference between the HTTP response status codes 301, 302, 307, and 308, given that they all redirect a client to a new location? (3)
Responda
  • Web servers may only send the status code 307 if the client made a request through HTTPS, whereas the code 301 is valid in HTTP and HTTPS
  • The status codes 307 and 308 return the new URI but explicitly instruct the client not to follow the redirect
  • The status codes 307 and 308 explicitly instruct the client to use the same method (GET or POST) when requesting the resource at the new location
  • The status code 308 explicitly instructs the client to use HTTPS rather than HTTP when requesting the resource at the new location
  • The status code 301 indicates that the resource has been moved permanently, whereas the code 302 indicates a temporary change
  • The status code 307 indicates that the resource has been moved temporarily, whereas the code 308 indicates a permanent change
