I am having issues with trying to set a cookie from a Response Header, I can see the set-cookie key with all the options that i have specified but for some reason it is not being set in the browser (Chrome).
I am setting the cookie using koajs, and reads as follows:
this.cookies.set(’test-cookie’, ‘valid’, { domain: ‘.test.io’, httpOnly: false, maxAge: 604800000 })
this is what I get in the response:
GET https://api.test.io/conversion
set-cookie: test-cookie=valid; path=/; expires=Mon, 12 Jun 2017 14:23:40 GMT; domain=.test.io;
I have another request (GET https://identity.test.io/identity) that does a similar request and has the same set-cookie response and i can see this cookie in chrome dev tools.
The only difference is api.test.io goes through several redirects (301), however we do not think that is the issue as we still see the set-cookie key in the final response header.
nb: this cookie needs to work across multiple sites which is why we don’t set secure, signed or httpOnly.
My answer is strictly for local testing, but I am putting it here as an answer cause your question is exactly what I searched for before I fixed it.
My php.ini file had the session.auto_start setting set to 0. I set it to 1, and the browser started saving cookies that were in response header. (using WAMP with PHP 7.0.29)

When I send a response from my server after authentication, I'm setting an authentication token cookie in the client's browser using this header:
Set-Cookie:mysite_auth=encodedJwtHere.JustPretend; SameSite=lax; domain=subdomain.mydomain.com; HTTPOnly; Max-Age=600; Secure; path=/
However, when I open EditThisCookie in Chrome, I can see that the domain is being set to .subdomain.mydomain.com automatically.
From what I thought I understood, this shouldn't be an issue. When I request https://subdomain.mydomain.com in the browser, the cookie is being sent.
My issue happens when I try to make a CORS request. I'm developing a javascript app and serving it on localhost. When I make an AJAX call to https://subdomain.mydomain.com, the cookie is not sent.
I have all of the proper headers set on the response:
Access-Control-Allow-Credentials:true
Access-Control-Allow-Headers:Content-Type, *
Access-Control-Allow-Origin:*
I have the {withCredentials:true} config on my request.
If I open https://subdomain.mydomain.com in the browser, then with EditThisCookie, I remove the prefix dot, I.E. I change .subdomain.mydomain.com to subdomain.mydomain.com, suddenly my AJAX calls from localhost work. The cookie is sent with the request.
So my question is, first of all, why is the cookie not being sent when there is a prefix dot, and is there a way to resolve this issue without manually editing the domain every time my cookie is refreshed?
If you're sending credentials, you can't respond with Access-Control-Allow-Origin:* - you must respond with a value that EXACTLY mirrors the Origin request header, e.g. Access-Control-Allow-Origin: {value-of-Origin-Header}.
In your case, that would presumably be Access-Control-Allow-Origin: https://subdomain.mydomain.com. Best not to hard-code it though - just mirror back Origin value.
the response header is
Access-Control-Allow-Credentials:true
Access-Control-Allow-Headers:Origin, X-Requested-With, x-request, Content-Type, Accept
Access-Control-Allow-Origin:*
Cache-Control:private
Connection:close
Content-Length:100

Server:nginx/1.2.8

X-Powered-By:node.js
X-Ua-Compatible:chrome=1
the cookie format's right (used cookie package to serialize ). the server is developed by node.js.
not only chrome, Firefox doesn't work too. the document.cookie is empty and also i can't see cookie in application section of chrome developer tool.
Any wrong in response header ?? Please help .
This problem occur due to multiple responses from server to client.
For example if you are sending a response to the server using response.send() and same time using
you are using response.setHeader()
This problem can be solve by creating cookie in client side using javascript.
And reading its value from node.js
The answer is because i used fetch() API that have to pass {credentials => 'same-origin'} option.
I'm very confused. I've got an AJAX call which causes a login form to be processed, and creates a cookie on a successful login. The web browser is not registering the cookie.
In troubleshooting, I isolated it down to something to do with the AJAX calling the site, rather than navigating directly.
e.g. I created a simple page "test" which returns the following output:
HTTP/1.1 200 OK
X-Powered-By: Express
Set-Cookie: token=ABCDEFG; Domain=localhost; Path=/
Content-Type: application/json; charset=utf-8
Content-Length: 19
ETag: W/"13-S4werj8PuppRlonJZs+jKA"
Date: Wed, 23 Sep 2015 22:09:03 GMT
Connection: keep-alive
{"message":"value"}
If I navigate directly to the page, the cookie is created in the browser.
If I make an AJAX call to the page, the cookie is not created in the browser.
e.g:
$.get('http://localhost:8081/test');
I've found similar posts which state that this happens with AJAX if the domain or the path are not defined, but as you can see, I defined these and still no dice.
If it matters, the majority of my testing has been on Firefox, but I did do at least a couple of tests on Chrome.
Any help you have would greatly be appreciated. I'm confused by this, as everything I read suggests this should be possible.
To clarify further:
1) I'm not seeing the cookie created when reviewing CookieManager+ addon for Firefox.
2) I'm also not seeing the cookie added to subsequent requests to the same host (even the same port).
3) What I read seems to suggest that cookies are tied to a host, not a port (But that doesn't seem to be the issue based on #1 and #2):
Are HTTP cookies port specific?
Try setting withCredentials in your request:
$.get('http://localhost:8081/test', {xhrFields: {withCredentials: true}});
Alternatively try setting the crossDomain value:
$.ajax({type:"GET", url:"localhost:8081/test", crossDomain:true});
If you're trying to do this in Angular, as I was, this is how you do it there:
$http doesn't send cookie in Requests
config(function ($httpProvider) {
$httpProvider.defaults.withCredentials = true;
I am trying to make connection with an API. When I call a method to this API, it respond with a cookie value sent via HTTP headers.
Will this header be automatically added to the client "my browser?" or do I have to parse the request first and create a cookie using setCookie?
if it does not add the cookies automatically, is there a way to do so?
It'll be handled automatically by your http client (you don't need to set it manually).
Server should respond with Set-Cookie header (not with cookie), then client will save that cookie, and send it on next requests.
Setting a cookie
Cookies are set using the HTTP Set-Cookie header, sent in an HTTP response. This header instructs the browser to store the cookie and send it back in future requests to the server (the browser will, of course, ignore this header if it does not support cookies or has disabled cookies).
As an example, the browser sends its first request to the homepage of the www.example.org website:
GET /index.html HTTP/1.1
Host: www.example.org
...
The server responds with two Set-Cookie headers:
HTTP/1.0 200 OK
Content-type: text/html
Set-Cookie: theme=light
Set-Cookie: sessionToken=abc123; Expires=Wed, 09 Jun 2021 10:18:14 GMT
...
The server's HTTP response contains the contents of the website's homepage. But it also instructs the browser to set two cookies. The first, "theme", is considered to be a "session" cookie, since it does not have an Expires or Max-Age attribute. Session cookies are typically deleted by the browser when the browser closes. The second, "sessionToken" contains an "Expires" attribute, which instructs the browser to delete the cookie at a specific date and time.
Next, the browser sends another request to visit the spec.html page on the website. This request contains a Cookie header, which contains the two cookies that the server instructed the browser to set.
GET /spec.html HTTP/1.1
Host: www.example.org
Cookie: theme=light; sessionToken=abc123
...
This way, the server knows that this request is related to the previous one. The server would answer by sending the requested page, and possibly adding other cookies as well using the Set-Cookie header.
The value of a cookie can be modified by the server by including a Set-Cookie header in response to a page request. The browser then replaces the old value with the new value.
The value of a cookie may consist of any printable ASCII character (! through ~, unicode \u0021through \u007E) excluding , and ; and excluding whitespace. The name of a cookie excludes the same characters, as well as =, since that is the delimiter between the name and value. The cookie standard RFC 2965 is more limiting but not implemented by browsers.
The term "cookie crumb" is sometimes used to refer to a cookie's name-value pair.
Cookies can also be set by scripting languages such as JavaScript that run within the browser. In JavaScript, the object document.cookie is used for this purpose. For example, the instruction document.cookie = "temperature=20" creates a cookie of name "temperature" and value "20".
See wikipedia page
Yes, the cookie will be added to document.cookie, unless the httponly param is set when sending the cookie.
I have a Flash application that sends a getURL request for an image file every 60 seconds.
This works fine in all browsers except IE9 with Internet Option set to automatically check for newer versions of stored pages.
I setup Charles proxy (http://xk72.com) to watch the requests being sent by my flash app and confirmed that the request is being surpressed by IE9 when the setting is set to Auto, but works fine if I change the setting to check everytime I visit the webpage. This, however, is not an option! I need this to work in all browsers regardless of how the options are set.
Even if I do a page refresh (F5), the ASP page does not reload. The only way to get it to reload is close the browser and restart it.
I have tried adding content headers to disable caching but it does not appear to work.
For Example, here is my request headers:
HTTP/1.1 200 OK
Date Sun, 02 Oct 2011 23:58:31 GMT
Server Microsoft-IIS/6.0
X-Powered-By ASP.NET
Expires Tue, 09 Nov 2010 14:59:39 GMT
Cache-control no-cache
max-age 0
Content-Length 9691
Content-Type text/html
Set-Cookie ASPSESSIONIDACQBSACA=ECJPCLHADMFBDLCBHLJFPBPH; path=/
Cache-control private
I have read the Microsoft blog (http://blogs.msdn.com/b/ie/archive/2010/07/14/caching-improvements-in-internet-explorer-9.aspx) which states that if I add the content headers, the browser should respect my request, but it obviously does not.
I don't think this is a Flash issue since the html page that holds the Flash object will not even reload.
You can append a random number to the end of the url.
