example.com and www.example.com are the same host by both fact and hence
definition. It is the domain being addressed not necessarily a physical
machine I agree. However...
The fact is that using www. as a prefix to a domain in order to
address a web server on that host may not be formal syntax but it is
formal by dint of common usage. Common usage for some time has been to
address the same host in either manner. Anyone reserving a domain today
will have both assigned and resolved as the same address making them
interchangable.
It is PHP that calls this a host and then provides 2 different answers as
to what that host is called during the same connection. The fact that it
comes up with 2 different answers to the same question during the same
connection should be telling you something?
That is a bug. And as big as a bug can get.
This makes PHP very much incorrect.
This is how the internet works. PHP needs to address this.PHP cannot
generate reliable sessions for all users until such time as this is
fixed.
In the mean time how about telling him how to avoid the bug?
