- Ha! There's a man who knows what's going on.... of course the slash just before
- the GET is interpreted as a gopher type character which happens to be
- invalid, so www just reads the document as plain text. With versiuon 1.1c or later
- (no, it's not released yet but I will if you want it), an "h" field means "html
- format". So I can say:(spot of the difference)

- File format
-
- The system uses marked-up text to represent a hypertext document when one is
- being stored in a file or transmitted over the network. Some of the formats
- available are illustrated in a test hypertext[1]. The hypertext mark-up
- language is an SGML format. This means basically that it uses angle brackets
- to delimit language constructs embedded within the text. The particular
- language 1 the set of tags and the rules about their use, and their
- significance 1 is not part of the SGML standard. There being no standard on
- this, we have adopted a set which seems sensible. Let's call them HTML --
- hypertext markup language. HTML is not an alternative to SGML, it is a
- particular format within the SGML rules (an SGML "DTD"). We have included in
- HTML tags from the SGML tagset used at and once supported at CERN by quite
- a lot of documentation and SGML examples.[2] The HTML parser will ignore
- tags which it does not understand, and will ignore attributes which it does
- not understand of CERN-SGML tags.

- Basically, Gopher addresses and w3 addresses are fairly interconvertable. And you
- are right, http and gopher protocols are very similar. [The "w" field can only be
- used in a gopher menu. It means "The selector string is in fact a w3 address, don't
- expect a port number or host address to follow it".]
