Domain: Web server can set cookies only for the domain that is pointing to that web server. It cannot set cookie for any other domain. However, JS code running on a browser can only access cookies set by its domain under which it is running. It cannot access other domain’s cookies.
1 Answer. You can’t share cookies across domains. You may share across subdomains. So, if your domain wrote the cookie stored on the client – whether in an iframe from other site or stored by visiting your main site, your domain should be able to access it.
Can you share cookies between domains?
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. Edit: You also want to avoid storing large amounts of data in a cookie.
When a page loads an from a cross-site origin, that frame is loaded in a third-party context, and any access to browser storage from within that will require the browser to allow third-party cookies for the
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.
Are cookies different for different browsers?
No. Cookies are stored in browser-specific files. A cookie is a piece of data that is sent from the server (web server) back to the client (browser). There is a contract between the two to that describes when the client should return the cookie back to the server on followup requests.
How to access parent domain from an iframe?
I need to access the Parent Domain URL from my Iframe which is in another domain. For example, “example.com” is my website which has an Iframe from another parent domain, such as “google.com”. Here I need to access the parent domain URL from my example.com.
Where do I find the iframe for example.com?
For example, “example.com” is my website which has an Iframe from another parent domain, such as “google.com”. Here I need to access the parent domain URL from my example.com. That is, I need to get the URL “google.com” in my “example.com” domain. Moreover, the Parent domain cannot be hard coded. but this results in Access denied error.
Can you share cookies across subdomains or domains?
1 Answer 1. You can’t share cookies across domains. You may share across subdomains. So, if your domain wrote the cookie stored on the client – whether in an iframe from other site or stored by visiting your main site, your domain should be able to access it.
Thus reading a cookie cross-origin from an iframe will only work if the content of the iframe explicitly communicates with the parent frame (like with postMessage) to share the cookie value.
