Cookies - set across multiple domains

Question

My company has a setup as follows:

• subdomain1.domain1.com
• subdomain2.domain1.com
• subdomain3.domain1.com
• subdomain4.domain1.com

Answer 1

Create a common domain specifically for your cookies and use it as a getter/setter API.

http://cookie.domain.com/set/domain1
http://cookie.domain.com/get/domain1

http://cookie.domain.com/set/domain2
http://cookie.domain.com/get/domain2

and so on.
