Setting cookies for another domain is not possible. If you want to pass data to another domain, you can encode this into the url. You can’t, at least not directly. That would be a nasty security risk.
Cookies are only accessible to a single domain that they are set to….Then the steps are simple:
- add to site A a hidden iframe to site B.
- send B’s cookie to A using window. postMessage.
- store the received cookie in A’s cookie.
Can cookies be accessed by other sites?
A properly designed browser will not allow a website to access another website’s cookies, as this would violate the cross-domain policy and be a major security issue.
Can Httponly cookies be stolen?
Because cookie data (and session IDs) can be stolen using Cross-Site Scripting (XSS), it is important to set cookies as being HTTPOnly. This setting makes cookies unavailable to JavaScript and prevents their theft using XSS. Cookies can also be configured as “secure cookies” or “https-only cookies”.
A third-party cookie placed on your machine at one site can be detected at a later time by the third party, so your browsing history is to some extent public. There are both HTML and Flash cookies, so if you wish to remove them delete both types.

Can a insecure site set cookies with the Secure attribute?
Insecure sites (with http: in the URL) can’t set cookies with the Secure attribute. However, do not assume that Secure prevents all access to sensitive information in cookies; for example, it can be read and modified by someone with access to the client’s hard disk (or JavaScript if the HttpOnly attribute is not set).
Where does a cookie go in an HTTP request?
We all know that a cookie is a small file residing in the client’s computer and stores data in plain text format. Whenever we make a HTTP request or response, we attach a cookie value with a HTTP message header. The cookie may contain user’s information and other necessary data.
To see stored cookies (and other storage that a web page can use), you can enable the Storage Inspector in Developer Tools and select Cookies from the storage tree. After receiving an HTTP request, a server can send one or more Set-Cookie headers with the response.
So, whenever the action dispatches the response, it will set the cookie with a response message. Another place to set the cookie is within the request response pipeline of the Web API. We know that every request and response passes through the channel and whenever a response is passed, we can attach a cookie to the header part.
