Here are some valid autolinks:
http://foo.bar.baz/test?q=hello&id=22&boolean
Uppercase is also fine:
Note that many strings that count as absolute URIs for purposes of this spec are not valid URIs, because their schemes are not registered or because of other problems with their syntax:
Spaces are not allowed in autolinks:
<http://foo.bar/baz bim>
Backslash-escapes do not work inside autolinks:
Examples of email autolinks:
Backslash-escapes do not work inside email autolinks:
<foo+@bar.example.com>
These are not autolinks:
<>
< http://foo.bar >
<m:abc>
<foo.bar.baz>
http://example.com
foo@bar.example.com
