absolute_url

Summary

absolute_url is a canonical absolute web URL.

Canonical form

An absolute_url value MUST:

• use the http or https scheme
• be entirely ASCII
• include a host of type domain_name
• not contain userinfo
• not contain a fragment
• not contain surrounding whitespace

The scheme and host MUST be lowercase.

If a port is present, it MUST be decimal digits only.

The default port MUST be omitted:

• :80 for http
• :443 for https

If the path is empty, it MUST be /.

Notes

absolute_url is a practical canonical form for Chronicle use.

This type does not attempt to represent every valid URI or URL form.
