The server has received the request headers and 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). Sending a large request body to a server after a request has been rejected for inappropriate headers would be inefficient.
In computing, POST is a request method supported by HTTP used by the World Wide Web. By design, the POST request method requests that a web server accepts the data enclosed in the body of the request message, most likely for storing it. [1] It is often used when uploading a file or when submitting a completed web form.
The PATCH request needs to use mechanisms such as conditional requests using Etags and the If-Match request header to ensure that data is not corrupted while patching. [1] In case of a failure of a PATCH request or failure of the channel or a timeout, the client can use a GET request to check the state of the resource. [ 1 ]
If you see an image challenge question when sending mail, you should just be able to complete the challenge then send mail. If, however, you correctly answer the image challenge and still can't send mail, it could be a sign of a more serious issue with your account, which may require additional steps to secure your account.
In contrast, the methods POST, CONNECT, and PATCH are not necessarily idempotent, and therefore sending an identical POST request multiple times may further modify the state of the server or have further effects, such as sending multiple emails. In some cases this is the desired effect, but in other cases it may occur accidentally.
Custom header fields can be added to the request to indicate how the server should fulfill it, [12] and data can be uploaded to the server by providing it in the "send" call. [13] The response can be parsed from the JSON format into a readily usable JavaScript object, or processed gradually as it arrives rather than waiting for the entire text ...
JSON streaming comprises communications protocols to delimit JSON objects built upon lower-level stream-oriented protocols (such as TCP), that ensures individual JSON objects are recognized, when the server and clients use the same one (e.g. implicitly coded in). This is necessary as JSON is a non-concatenative protocol (the concatenation of ...
If a Transfer-Encoding field with a value of "chunked" is specified in an HTTP message (either a request sent by a client or the response from the server), the body of the message consists of one or more chunks and one terminating chunk with an optional trailer before the final ␍␊ sequence (i.e. carriage return followed by line feed).
