Note: When automatically redirecting a POST request after receiving a 301 status code, some existing HTTP/1.0 user agents will erroneously change it into a GET request. 10.3.3 302 Found The requested resource resides temporarily under a different URI. Except when responding to a HEAD request, the server SHOULD include an entity containing an explanation of the error situation, and whether it is a temporary or permanent condition. If you go a different route, I would suggest making the library HTTP 1.0/1.1 aware first. See section 8.2.3 for detailed discussion of the use and handling of this status code. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. this contact form
DNS) it needed to access in attempting to complete the request. Otherwise (i.e., the conditional GET used a weak validator), the response MUST NOT include other entity-headers; this prevents inconsistencies between cached entity-bodies and updated headers. The status codes 303 and 307 have been added for servers that wish to make unambiguously clear which kind of reaction is expected of the client. 10.3.4 303 See Other The response to the request can be found under a different URI and SHOULD be retrieved using a GET method on that resource. However, most existing user agent implementations treat 302 as if it were a 303 response, performing a GET on the Location field-value regardless of the original request method. https://en.wikipedia.org/wiki/HTTP_302
You signed out in another tab or window. The server MUST send an Upgrade header field in a 426 response to indicate the required protocol(s) (Section 6.7 of [RFC7230]). 428 Precondition Required The origin server requires the request to be conditional. Check out this https://post.craigslist.org/c/hou?lang=en Now the form is destined for this resource: https://post.craigslist.org/k/
These can provide additional information about the new URL(s) which the Web server thinks we should be accessing. changing the verb is OK for browsers, but way too magical for a programmatic http client. URL A redirects to URL B which in turn redirects back to URL A.

User-agent or user should choose one of them. However, this specification does not define any standard for such automatic selection. The response MUST include the following header fields: - Date, unless its omission is required by section 14.18.1 If a clockless origin server obeys these rules, and proxies and clients add their own Date to any response received without one (as already specified by [RFC 2068], section 14.19), caches will operate correctly. - ETag and/or Content-Location, if the header would have been sent in a 200 response to the same request - Expires, Cache-Control, and/or Vary, if the field-value might differ from that sent in any previous response for the same variant If the conditional GET used a strong cache validator (see section 13.3.3), the response SHOULD NOT include other entity-headers. The new URI is not a substitute reference for the originally requested resource.
Because, it isn't now... The response MAY include new or updated metainformation in the form of entity-headers, which if present SHOULD be associated with the requested variant.

All clients (including curl) have to send the slash after the domain name as part of the HTTP request whether or not it is on the URL. Except when responding to a HEAD request, the server SHOULD include an entity containing an explanation of the error situation, and whether it is a temporary or permanent condition.

My guess would be that doing a couple of redirects to itself is seamless for standard-behaving clients, but might be problematic for some broken bots, and GitHub might be using it as a technique to avoid some email harvesters or some such? My patch seeds that ability with options.approveRedirect, a separate state from followRedirect. EvanCarroll commented May 24, 2011 Bad idea, it would forever remove the ability to have a true HTTP 1.0, or HTTP 1.1 compatible client. navigate here Our really simple guide to web hosting (getting your web site and email addresses on the Internet using your own domain name).

Http 302 Error Smite The new permanent URI SHOULD be given by the Location field in the response. Or perhaps it is to minimise bandwidth use by giving a redirect to non-browser clients which might not bother to make a second request?
The temporary URI SHOULD be given by the Location field in the response. They'll wonder why they get "redirects" sometimes and not other times.

Unless it was a HEAD request, the Entity-Body of the response should contain a short note with a hyperlink to the new URI(s). This response is used much more since some browsers, like Chrome or IE9, use HTTP preconnection mechanisms to speed up surfing (see bug 881804, which tracks the future implementation of such a mechanism in Firefox). his comment is here If the client is sending data, a server implementation using TCP SHOULD be careful to ensure that the client acknowledges receipt of the packet(s) containing the response, before the server closes the input connection.
I'm going to create an option for this functionality and default it to enabled, per the expected behaviors. The request.defaults call can be used to return a wrapper around the request module that changes the defaults, so using "browser mode" all the time would only be a one line code change. How to know if a meal was cooked with or contains alcohol? A client is recommended to continue a Request URL for any future requests and a response of this nature is only cached when indicated by the Expired field header or a Cache Control command.
Even the spec makes notes of the implementations breaking it. I just don't think that it should be the default. If the 302 status code is received in response to a request using the POST method, the user agent must not automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued. This has the same semantic than the 302 Found HTTP response code, with the exception that the user agent must not change the HTTP method used: if a POST was used in the first request, a POST must be used in the second request. 308 Permanent Redirect This means that the resource is now permanently located at another URI, specified by the Location: HTTP Response header.

HTTP 302 redirects GET->GET transparently in the spec, Request.js, and the browser; but, if you post to something that redirects HTTP 302 all browsers mistakenly do this automatically, the spec requires user validation on the redirect, and Request does this through an additional option. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s). The HTTP/1.0 specification (RFC 1945) initially defined this code, and gives it the description phrase "Moved Temporarily".

The newly created resource can be referenced by the URI(s) returned in the entity of the response, with the most specific URI for the resource given by a Location header field. My suggestion is that we have two modes, one which permits some sort of functionality to obtain API approval, and another that automatically approves.
