refer to the target resource and its selected representation after the requested action was applied. For example, http error code 406 if a 204 status code is received in response to a

PUT request and the response contains an ETag header field, then the PUT was successful

and the ETag field-value contains the entity-tag for the new representation of that target resource. The 204 response allows a server to indicate that the action

has been successfully applied to the target resource, while implying that the user agent does not need to traverse away from its current "document view" (if any). The server assumes that the user agent will provide some indication of the success to its user, in accord with its own interface, and http/1.1 409 conflict apply any new or updated metadata in the response to its active representation. For example, a 204 status code is commonly used with document editing interfaces corresponding to a "save" action, such that the document being saved remains available to the user for editing. It is also frequently used with interfaces that expect automated data transfers to be prevalent, such as within distributed version control systems. A 204 response is terminated by the first empty line after the header fields because it cannot contain a message body. A 204 response is cacheable by default; i.e., unless otherwise indicated by the method definition or explicit cache controls1. 1 Calculating Heuristic Freshness RFC7234 Section 4.2.2 Source: RFC7231 Section 6.3.5 204 Code References Rails HTTP Status Symbol :no_content Go HTTP Status Constant http.StatusNoContent Symfony HTTP Status Constant Response::HTTP_NO_CONTENT Python2 HTTP Status Constant httplib.NO_CONTENT Python3+ HTTP Status Constant http.client.NO_CONTENT Python3.5+ HTTP Status Constant http.HTTPStatus.NO_CONTENT← Return to httpstatuses.com

Like, is this semantically correct with respect to what an HTTP GET is supposed to accomplish? I know that a 204 - No Content is okay for an HTTP POST Request. For GET request, if no data is to be sent back, is http://stackoverflow.com/questions/12807753/http-get-with-204-no-content-is-that-normal the 204 status code appropriate? Should I use 404, or just stick to 200 for success but have an empty response? The use case for this question is a Java application that I am writing for Google App Engine. I am sending a request to a servlet, but the data to be sent back to the client will be transmitted through a Channel API socket instead of in the HTTP Response. Currently, my client sends a POST with no content in the request body, and waits for a 204 response back from the servlet before polling the Channel API socket. Because no data I being sent in the body of the request, I am debating whether it makes more sense for me to send a GET instead of a POST. google-app-engine http get http-status-codes channel-api share|improve this question edited Sep 15 '14 at 14:17 Tshepang 4,6941059103 asked Oct 9 '12 at 20:16 ecbrodie 3,52183677 add a comment| 2 Answers 2 active oldest votes up vote 29 down vote accepted 204 No Content The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation.

205 Reset Content The 200 range of HTTP status codes represents successful requests. I’ve already covered 201 Created and 202 Accepted and 206 Partial Content. Today, I’ll wrap up my https://benramsey.com/blog/2008/05/http-status-204-no-content-and-205-reset-content/ discussion of the 200 range by talking about 204 No Content and 205 https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/204 Reset Content. The 200 OK response is probably the status with which most are familiar, and I’ll discuss it later when covering the HTTP verbs. The 204 No Content response is useful in a web service when you want to return a success message but do not want to return http error a message in the body or do not have a body to return. In my personal experience, I use this when DELETE requests are sent to an Atom web service. If the resource is successfully deleted, the service returns a 204 No Content status message. This tells the client that the deletion was successful, and that’s really all the client needs to know. http error code There’s nothing to return because it was deleted. However, even outside of the web services realm, the 204 No Content status actually means something to a user agent (browser). The HTTP specification (RFC 2616) states the following about the 204 No Content status code: If the client is a user agent, it SHOULD NOT change its document view from that which caused the request to be sent. This response is primarily intended to allow input for actions to take place without causing a change to the user agent’s active document view, although any new or updated metainformation SHOULD be applied to the document currently in the user agent’s active view. This means that, if I have an HTML form and submit it, then, if the server returns a 204 status code, the browser should not refresh the form or take me to another page. The document view does not change, and I remain at the form. All of the data I entered remains unchanged. All browsers I tested support this, but, in practice, it is not very useful since there’s no indication to a user that anything happ

A 204 response is cacheable by default. An ETag header is included in such a response. The common use case is to return 204 as a result of a PUT request, updating a resource, without changing the current content of the page displayed to the user. If the resource is created, 201 Created is returned instead. If the page should be changed to the newly updated page, the 200 should be used instead.
