Hi fahad, I may be a little bit confused, so maybe you are able to explain a little bit more to me. Are you talking about cookies not shared between subfolders, or between subdomains?
According to the original Netscape Cookie specification, sharing between different sub domains must be possible, even if the tail of the domain contains more than one step. For example def.xyz.abc.example.com and xyz.def.abc.example.com should receive the same cookies, if the cookie domain has been set to .abc.example.com.
