title: Chrome Set Cross Domain Cookie
body: <p>My site is a.com and I want to create a cookie in b.com.</p>
  
  <p>I try to set a cross domain cookie using an ajax request to b.com and returning a set cookie header. 
  If I go directly to b.com the cookie is set, but it doesn't set it through the ajax request although I see the cookie set command in the developer tools. Iframe is not an option since I send the cookie data in a post request</p>
