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.
Can we share cookies across domains?
Cookie is not shared among different browsers. Means, one browser cannot read the cookie stored by another browser even if it is same domain. As per HTTP protocol, size of the cookies cannot be greater than 4KB. Number of cookies sent by web server for a given domain cannot be unlimited.
How do I send secure cookies?
When using cookies its important to remember to:
- Limit the amount of sensitive information stored in the cookie.
- Limit the subdomains and paths to prevent interception by another application.
- Enforce SSL so the cookie isn’t sent in cleartext.
- Make the cookie HttpOnly so its not accessible to javascript.
1) attach an iFrame using the userscript, which loads a site on domain2. This then uses the querystring to decide what to set to what, or; 2) use a form with method=”POST”, and simply post to a file on each domain.
Do cookies get sent with every request?
Cookies are sent with every request, so they can worsen performance (especially for mobile data connections). Modern APIs for client storage are the Web Storage API ( localStorage and sessionStorage ) and IndexedDB.
Can cookies be shared by domains?
8 Answers. Two different domains (e.g. mydomain.com and subdomain.mydomain.com , or sub1.mydomain.com and sub2.mydomain.com ) can only share cookies if the domain is explicitly named in the Set-Cookie header. Otherwise, the scope of the cookie is restricted to the request host.
You cannot share cookies across domains. You can however allow all subdomains to have access. To allow all subdomains of example.com to have access, set the domain to .
How do cookies work in different domains?
Can HTTP cookies belong to multiple domains?
1 Answer. A cookie can only have 1 domain value. So you can either set it to a specific domain or the top domain wich includes all the subdomains.
HTTP cookies currently in use are governed by the same origin policy that directs Web browsers to allow cookie sharing only between Web sites in the same DNS domain. As Web applications get richer, data sharing across domain boundaries becomes more important.
Is it possible to share cookies between two websites?
Cookies are only accessible to a single domain that they are set to. I believe if you are using two sub-domains on the same domain it would be possible to share the cookies, however the browser doesn’t send cookies set on one domain to any others.
How to securely set a cookie on another?
I’m aware of a few approaches: hub sets the cookie on example.com This works, but the cookie propagates to other subdomains. Also a risky subdomain like lab could set the cookie. learn provides a setCookie controller.
To set cookies Web servers use the Set-Cookie HTTP header; to relay cookies to Web servers browsers use the Cookie header c. One of the requirements of the same origin policy is that cookies be shared only between Web sites within the same administrative domain.
