There are cases where case insensitivity should not apply. However, the
specification says URLs are case sensitive, and there are applications
where case sensitivity matters and is used on a daily basis (YouTube).
At minimum, if a server application is going to act in a case
insensitive fashion, it should 301 redirect to either the correct case
or a canonical case, rather than just blindly returning the same 200
response to two different URLs that in reality point to the same
document. (This is so caching proxies only cache one copy.)
