Many browser engines use lists of top-level domains to be able to
determine what a server's "base domain" is. For some use cases it would be
interesting to have this information available to scripts. I list some use
cases I can think of below:
1) Determining in a simple and fool-proof manner that a page is from a
given domain. For example, if a script that might run on *.example.com,
*.example.co.uk etc can do
if(location.domain.indexOf('example.'==0) to check whether it runs on an
*.example.* site (and not get a false positive match on
example.exmple.com).
2) Checking what the shortest possible string for document.domain is.
3) Set cookies for all servers in a domain easily from JS without specific
string operations on the hostname
Thoughts?
