HTTP response code shows that a HTTP request has been completed with some codes like 200, 201 etc. We can understand it like when a client or user request to server and then server give them some response with code. Using code , we can deduct that server response is success or fail or server side error etc easily but we need some technical knowledge in HTTP so we are going to discuss here about some technical things related to HTTP response codes.
HTTP have many response code list but we can group it.
- Informational responses (100–199)
- Successful responses (200–299)
- Redirects (300–399)
- Client errors (400–499)
- Server errors (500–599)
1. Informational responses (100–199)
