The (www url)
module provides procedures for high-level url
object conversion, low-level url object construction and access,
and character decoding/encoding.
Parse string and return a url object, with one of the following "schemes": HTTP, FTP, mailto, unknown.
Return the url object formatted as a string. Note: The username portion is not included!
Construct a url object with specific scheme and other args. The number and meaning of args depends on the scheme.
Construct a HTTP-specific url object with host, port and path portions.
Construct a FTP-specific url object with user, host, port and path portions.
Construct a mailto-specific url object with an address portion.
Extract and return the "scheme" portion of a url object.
url:scheme
is an unfortunate term, but it is the technical name for that portion of the URL according to RFC 1738. Sigh.
