What does the term ‘absolute URL’ refer to?
The RFCs indicate that the scheme is required in an absolute URL, making
https://example.com/foo/cat.gif
an absolute URL.
But cat.gif
and /foo/cat.gif
are both URLs, with one relative and the
other absolute, so one of them is an absolute URL, even though it’s not
the ‘absolute URL’ of the RFCs.
