LYNX-DEV Traversing LYNXIMGMAP:http://server/file#fragment URLs

        I sent Hiram replacement files for the following:
        
10-20-96
* Added code for traversing the pseudo-documents created for client-side
  image MAPs.  See the updated CRAWL.announce for more information. - FM


        Traversals of client-side image maps based of FIG or OBJECT
are automatic, with the same regulation based on realm as for other
http URLs.  The internal URLs for the pseudo-documents created for
MAPs have the following format:

        LYNXIMGMAP:scheme://host/path#MAP_NAME_attribute_value

The new code will check the realm based on the proxy-like field
following the LYNXIMGMAP: internal scheme.  If you include -crawl
it will not create an lnk########.dat file for the pseudo-document,
just the real documents fetched via http URLs from the HREFs of
AREA tags in the MAP.

        Yes, the "internal" URL scheme will work externally as
the startfile, e.g.:
        
        lynx LYNXIMGMAP:http://www.wfbr.edu/#mainmenu

but, no, that's not allowed as a startfile for traversals.  It
could be made so, but didn't seem like a good idea to me, so I
didn't add support for that.  If you *really* want it, make a
compelling case for it.  The logic would have to be that the
proxy-like URL following the LYNXIMGMAP: internal scheme would
be used for setting the realm field to regulate where the
traversal could go.
