Is WebSocket same as HTTP?
WebSocket: WebSocket is bidirectional, a full-duplex protocol that is used in the same scenario of client-server communication, unlike HTTP it starts from ws:// or wss://. When the connection is established and alive the communication takes place using the same connection channel until it is terminated.
What are the different types of HTTP status codes?
Responses are grouped in five classes:
- Informational responses ( 100 – 199 )
- Successful responses ( 200 – 299 )
- Redirects ( 300 – 399 )
- Client errors ( 400 – 499 )
- Server errors ( 500 – 599 )
What does status line mean in WebSocket server?
This is followed by a set of key-value header pairs that provide the client with reciprocal information from the server, with respect to the request that the server is responding to. The Status-Line tells the client the HTTP status code (usually 200 if there were no problems).
How is a WebSocket similar to an HTTP Server?
WebSockets share some HTTP details – they have a path and headers – but also have more state. Again, most of that state is in the scope, which will live as long as the socket does. WebSocket protocol servers should handle PING/PONG messages themselves, and send PING messages as necessary to ensure the connection is alive.
Can a bad request be a HTTP status code?
You can use “Bad Request” and include the id of the violated business rule plus some more details on the body of the response. Generally, I would avoid using HTTP status codes to represent specific business logic errors. This is because they already have a semantic meaning that is defined by the world-wide standard.
What does it mean when a HTTP response code is sent?
This interim response indicates that everything so far is OK and that the client should continue the request, or ignore the response if the request is already finished. This code is sent in response to an Upgrade request header from the client, and indicates the protocol the server is switching to.
