Which HTTP status code is usually returned when the resource is cached?
304 means Firefox is sending a “If-Modified-Since” conditional request to the Web server. If the file has not been updated since the date sent by the browser, the Web server returns a 304 response which essentially tells Firefox to use its cached version.
Is HTTP 304 an error?
An HTTP 304 not modified status code means that the website you’re requesting hasn’t been updated since the last time you accessed it. Usually, you’ll only see this error code if you’re on a search engine because search engines index and cache websites. …
When to use HTTP response code when resource already exists?
The request could not be completed due to a conflict with the current state of the resource. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request. The response body SHOULD include enough information for the user to recognize the source of the conflict.
What can a 303 status code do for a REST API?
Generally speaking, the 303 status code allows a REST API to send a reference to a resource without forcing the client to download its state. Instead, the client may send a GET request to the value of the Location header.
Is it correct to return 404 when a rest resource is not found?
Yes, it is pretty common to return 404 for a resource not being found. Just like a web page, when it’s not found, you get a 404. It’s not just REST, but an HTTP standard.
What does it mean to request a rest resource?
But requesting a REST resource and more particularly by a GET method doesn’t mean that the client is about terminating a workflow (that makes more sense with POST/PUT methods). 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.
