8.2 Gopher URLs
Gopher servers can be accessed via URLs in a manner similar
to HTTP servers. The major
difference is in the file specification: here we must pass the
correct descriptors for the file (searchable, directory, etc),
as required by the gopher protocol. These are specified by
numeric codes specified in the path name, before the name
of the file being accessed. The gopher numeric type indicators
are:
- 0 - Text file
- 1 - Directory
- 2 - CSO Name Server
- 4 - Mac *.hqx file
- 5 - Sound file
- 7 - Full text index
- 8 - Telnet session
- 9 - Binary file
8.2.1 Gopher URL Examples
- gopher://gopher.hprc.utoronto.ca/
- Retrieve the home menu from the named gopher server, running
on the default port number (70).
- gopher://gopher.hprc.utoronto.ca/11adaptive.technology
- Retrieve the 'adaptive technology' menu from the named gopher
server, running on the default port number.
- gopher://gumby.brain.headache.edu:151/7fonebook.txt
- Access the searchable index 'fonebook.txt' from the named
gopher server, running on port number 151.
Gopher URLs are complicated, and easy to mess up. The easiest way to
create them is to use your computers's cut and paste feature -- use your
browser to access the document you want, cut out the URL, and then paste it
into your HTML document!
