Where do you get this from?

Do you mean "though different HTTP URIs are different URIs"?




...both address (or fail to address) the same thing.

If you want to consider these different "addresses" (for potentially the 
same thing), you're welcome. But the rules of HTTP URIs mean that 
there's nothing named (addressed) by the one but not by the other. 
Domain names are case insensitive, and HTTP URIs default to port 80.

There are other situations where we might say a pair of HTTP URIs happen 
accidentally (perhaps for a while, perhaps forever) to be for the same 
underlying thing. But the example above is one in which they simply are 
different ways of writing the same thing.
