Domain names are not case sensitive (ie the DNS system is not case
sensitive).  All the rest of the URL depends on the web-server, and
thus usually is considered case-sensitive as most webservers are
UNIX/Linux/BSD and their filesystems are case-sensitive.  Windows
servers are likely not sensitive to case, but I still would always
consider the path part of the URL case-sensitive even if working on
one of those.
