- (If there's a better forum for discussion of URLs, let me know.)
-
- At the Gopher conference this Monday, a few people tried to convince
- the UMN Gopher team to alter Gopher+ to use URLs. (I wasn't one of
- them, but I agreed.) Having done a little hacking today on the
- gopher-handling part of w3.el, though, I'm wondering about the
- interaction of two facts:
-
- >The path is interpreted in a manner dependent on the protocol being used.
- >However, when it contains slashes, these must imply a hierarchical structure.
- (from the URL spec)
-
- but the Gopher protocol insists on the opacity of selector strings.
- That is, if a Gopher selector string is "fumble/foo/.././bar/../baz", it
- is *just that*, not "fumble/baz", which URL interpreters would come up
- with.
-
- I think this could be gotten around by quoting slashes in the path
- part of a URL, although I'm not quite sure where the unquoting takes
- place, so this might not work. However, this seems unnecessary to me.
- I guess what I want to ask is, why is any URL that contains a slash
- forced into a hierarchical interpretation? I would prefer that
- specific schemes (http, ftp, afs, prospero?) be classified as
- hierarchical, and hierarchy-based translations be limited to those
- schemes. New schemes, as they appear, can specify whether or not they
- follow the standard hierarchical-structure rules.
-
- This implies, of course, that if a client isn't familiar with a given
- scheme, of course, it can't know whether or not to perform
- translations on URLs in that scheme. I'm not convinced that this is a
- bad thing--if a program doesn't understand an address, it can just
- pass it off to another program (e.g., a gateway) that does.
-
- So, what am I overlooking? I realize this would require clients to
- store an additional piece of information for each scheme (hierarchical
- bit), but this doesn't seem like a great cost to me in exchange for
- some opacity of paths.
