See the following document for more info on URLs:
"Names and Addresses, URIs, URLs, URNs, URCs", at
http://www.w3.org/pub/WWW/Addressing/Overview.html
See also the HTTP spec (from which the error codes are derived):
"HTTP - Hypertext Transfer Protocol", at
http://www.w3.org/pub/WWW/Protocols/
Related standards and specs:
- RFC1808: the "relative URL" spec. (authoritative status)
- RFC1738 - the "URL standard". (authoritative status)
- RFC1630 - the "URI spec". (informational status)
The object returned by URLopener().open(file) will differ per
protocol. All you know is that is has methods read(), readline(),
readlines(), fileno(), close() and info(). The read*(), fileno()
and close() methods work like those of open files.
The info() method returns a mimetools.Message object which can be
used to query various info about the object, if available.
(mimetools.Message objects are queried with the getheader() method.)

This is a class rather than just a subroutine because we may need
more than one set of global protocol-specific options.

Each part of a URL, e.g. the path info, the query, etc., has a
different set of reserved characters that must be quoted.
RFC 2396 Uniform Resource Identifiers (URI): Generic Syntax lists
the following reserved characters.
reserved = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" |
"$" | ","
Each of these characters is reserved in some component of a URL,
but not necessarily in all of them.
By default, the quote function is intended for quoting the path
section of a URL. Thus, it will not encode '/'. This character
is reserved, but in typical usage the quote function is being
called on a path where the existing slash characters are used as
reserved characters.

If any values in the query arg are sequences and doseq is true, each
sequence element is converted to a separate parameter.
If the query arg is a sequence of two-element tuples, the order of the
parameters in the output will match the order of parameters in the
input.
