   gopher://iubio.bio.indiana.edu:71/

This is a variant of U.Minnesota's gopherd server, version 2.014.
It includes changes applied by Don Gilbert, gilbertd@bio.indiana.edu.
These include basic HTTP/HTML server support, so this server can
be run as a dual gopher+/http server;  it includes support for freewais-sf
variant of wais search software; it includes various gopher+ patches
and other changes used at IUBio archive (gopher/http to iubio.bio.indiana.edu)

This server provides one view of the same file system to gopher+ and http 
clients.  It includes a few special features for modifying that: 
  the filename.abstract block adds descriptions to html directories,
  the filename.nohtml block hides an item like gopher+ ask dialog from
    html clients
  the filename.onlyhtml block hides an item like html forms from
    gopher clients

The "linkdir" addition adds a symbolic linked folder to the current
server folder (e.g., to link in an ftp file system w/o putting gopher/http
forms in the ftp area):

Add this kind of item to gopherd.conf:
#
# any sub-folder with this name will be automagically listed in current folder
# use w/ symbolic linked ftp-area folders into gopher-area folders
# to avoid putting gopher-junk in ftp area (dgg addition)
#
linkdir: link.dir

Then add symbolic links with name "link.dir" to server folders.

There is an "exec+" server type (gopher type) that I use extensively
with any kind of form, because it expands the "exec:" type to include
gopher+ view parsing and a few other additions. Consider it like HTTP's
CGI subprograms.

Link format is 
  0Title<tab>exec+:some commandline params here:/path/to/handler<tab>host<tab>port
or
  1Title<tab>exec+:....

The exec+ responds to gopher+ "!" and "$" and also can return type 1 (folder)

Note: this is not an official distribution, and I don't have much time
to spare providing support for it at present.  I've used it on SunOS 4.1.2
and DEC Alpha OSF/1 systems.  

This is the call that I use to run the http variant of this
server from SunOS inetd (-H forces http/html services, it supports
basic GET and POST variants of http, including http forms):

/usr/local/etc/gopherd -HIcu gopher -o /usr/local/etc/gopherd2.conf \
  -l /usr/tmp/http.log /bio/gopher/public2 80
