AngularJs: How to set same cookie on different domains

Question

I have 2 domains:

www.site1.com
www.site2.com

Important Notes:
not sub domain!
Allow-Origin are enable on both domains.
have full Access to both of domains.

Question:

How to set a cookie on site1 & get that cookie on site2 ?

I want to use it on AngularJs, no matter if using jQuery in your examples.

@SharnWhite, no It's ASP.NET, in that example i think we should put some file from site2 to site1 for doing proccess on cookies. — Maher, Jun 08 '16 at 05:43

Yep, i image you can do something similar to 'Cross-domain-cookies - a maybe new idea', but via an asp script. — Sharn White, Jun 08 '16 at 05:51

There is a technique that multi-site companies like google employ to keep their users logged in for all their sites per single authentication.

This question is about how A can read a cookie of B. But my answer only tells you how A can set a cookie in B. Although this technique can be employed in a useful way for OPs favor, negative points are welcome. I will still spread the awareness.

Create a php file (lets say setcookie.php) in site B. This can set a cookie for site B.

setcookie("MyCookie", "subinsb.com", time()+3600);

Now if you can call this php file from any site, it will set the cookie for site B. A famous way to call this script is via a hidden img tag. So, the site A can have this image tag - which will set a cookie for site B.

<img src="http://www.siteB.com/setcookie.php" style="display:none;" />

When this image is loaded, you know the cookie for site B is set.

Interestingly, you can send data too to the cookie of site B through the URL. Your setcookie.php can read data via $_GET and include them in the cookie.

Here is the article.

Hi, no need to negative points! :) , thank you ; but i already use ASP.NET. — Maher, Jun 08 '16 at 06:42
I'm sure you can do in asp.net the same thing the php does. It's http protocol after all. — Charlie, Jun 08 '16 at 07:03
