I was brought aware of this issue by some users on my website. A user many enter into their browser http://xxxx.com and then login. Then they may click on a link that brings them to http://www.xxxx.com it asks them to login again! Is this a known issue that anyone has encountered before? I tried googling it but im not sure if im using the wrong keywords or what because i cannot find anything related to this.
Thanks,
Ian McCullough
As far as your browser is concerned, http://www.xxxx.com and xxxx.com are different domains. The same-origin policy prevents accessing cookies across domains.
However, the browser is aware of subdomains, and a subdomain can access the cookies of a parent domain. So, if you want to make your cookie accessible to both xxxx.com and http://www.xxxx.com, just set your cookie on .xxxx.com and you’ll be set.
