Netizen tentunya sudah pernah menjumpai beberaapa respon http dari server-server akan akses, seperti 503 Service Unavailable, 401 Unauthorized, dll.
Kode-kode respon http tersebut ada banyak, dimana masing-masing dari kode tersebut mempunyai arti yang berbeda. Beberapa mungkin sudah kita ketahui.
Berikut ini saya coba listing beberapa kode respon status HTTP :
1xx Informational
Request received, continuing process.
This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. Since HTTP/1.0 did not define any 1xx status codes, servers must not send a 1xx response to an HTTP/1.0 client except under experimental conditions.
100 Continue
This means that the server has received the request headers, and that the client should proceed to send the request body (in the case of a request for which a body needs to be sent; for example, a POST request). If the request body is large, sending it to a server when a request has already been rejected based upon inappropriate headers is inefficient. To have a server check if the request could be accepted based on the request’s headers alone, a client must send Expect: 100-continue as a header in its initial request and check if a 100 Continue status code is received in response before continuing (or receive 417 Expectation Failed and not continue).
