I am trying to create url like sub2.sub1.subdomain.domain.com. I am planning to use this to display different content.
my questions are...
1) Is it possible to create such multi level sub domains? - is this based on the hosting company?
2) Isn't sub2.sub1.subdomain a different subdomain rather than a sub domain of sub1?
3) Will all of these subdomains have their own doc roots?
4) How will I handle users coming with and without www.
Any other potential issues that might arise?
EDIT:- How does this affect the behaviour of cookies? Can I access a cookie set on subdomain.domain.com on sub1.subdomain.domain.com or sub2.sub1.subdomain.domain.com
