Implementations: Code, Docs

Notes on implementations and how they're described and specified -- i.e. shared context in the developer community. Also bugs.

Hmm... it would be nice if URI access libraries supported A DNS RR for specifying the location of services (DNS SRV), wouldn't it?

The HTParse, HTEscape modules in LibWWW

features:

• parse aName relative to relatedName, returning requested parts: access[sic], host[sic], path, anchor (punct: with or without delimiters... huh??).
• "subtract" urls, i.e. compute a relative URI from one absolute URI to another.
• canonicalize URLs: only reduces stuff like /a/b/../c to /a/c
• isAbsolute: see if there's a : before any occurence of /, ?, or #.
• escaping/unescaping %XX. But the set of characters to escape is fixed (wel... there are flags for + and /).

scheme specific processing: removing :80 from http:, lower-casing domain names in news:...@foo.bar.

processing that should be scheme-specific but isn't: looking for hostnames when doing "subtraction". lowercasing domain names.

URI scheme was originally referred to as the "access scheme" -- failure to realize the myth of names and addresses. Now called simply the URI scheme (see comment in HTParse.c.

Hmmm... anchors survive relative combination? e.g. x:foo#bar + blot = x:blot#bar?

Microsoft Docs

Argh!

Surround the hyperlink with angle brackets, because it contains spaces

Netscape 3.0

Wild! Try this one: an IRC channel.

NS fails to recognize it as an absolute URI!

See also: the bug involving fragment ID's and HTTP redirection. (seems to be fixed in NS 3)

JDK 1.1 URL class

Cites only NCSA docs! Not IETF RFCs at all!

terminology is not abstract at all: protocol, host, port, file, file.
