 Folks,

 we're pleased to announce the availability of our SOLO protocol module for
the libwww: HTSolo.c

 People who didn't attend my (suffering ;-) presentation at WWW'94 will find
more information about this work in the related paper:

	http://champagne.inria.fr/~touvet/SOLOWWW/last.html

 This module resolves the following URLs:

	solo:ESCAPED_SOLO_QUERY			Using a default SOLO centroid
    ex. solo:%3Chuitema,inria,fr%3E?email

	solo://server/ESCAPED_SOLO_QUERY	Using a given server
    ex. solo://champagne.inria.fr:2222/%3Cpays%3E?*

	x500:ESCAPED_SOLO_QUERY			Using a SOLO front end to X.500
    ex. x500:%3Chowes,*michigan*,us%3E?*

	When no query is specified, a FORM is returned.

 We added too, FOR EXPERIMENTAL PURPOSE ONLY:

	urn:USER_FRIENDLY_NAME			Using a SOLO URC centroid
    ex. urn:solo-www%20paper,inria,fr

 Optional environment variables:

	SOLO_DEFAULT		name[:port] of nearest SOLO centroid
	WWW_x500_GATEWAY	URL of nearest SOLO front-end to X.500
	WWW_urn_GATEWAY		URL of nearest SOLO URC centroid

	Default settings are currently:

		SOLO_DEFAULT=pax.inria.fr
		WWW_x500_GATEWAY=x500://champagne.inria.fr:2222/
		WWW_urn_GATEWAY=urn://champagne.inria.fr:2222/

 HTSolo.c was successfully integrated into:

	NCSA's Mosaic for X, version 2.4 (libwww/2.12 modified)
	Lou Montulli's Lynx, version 2.3 (libwww/2.14)

 on a sun4, and we hope that people will try it with other browsers and
servers in proxy mode...

 The distribution directory is:

	http://champagne.inria.fr/Pub/

 Files:

	Mosaic-solo.Z		Mosaic binary for sun4 (-lresolv) [1.3 Mb]
	lynx-solo.Z		Lynx binary for sun4 (-lresolv) [0.5 Mb]
	test.html		Some examples
	README			This announce
	Mosaic-solo.tar.Z	Source+diffs for Mosaic & libwww/2.12 modified
	lynx-solo.tar.Z		Source+diffs for lynx & libwww/2.14

 WARNING:

	Binaries are just provided for testing purpose, and direct WAIS access
	is not included in them. The SOLO_TRACE flag is up in Mosaic-solo, so
	you'll get debugging info while testing the new module.

 Compiling with other browsers/servers:

	 It mainly depends on the version of libwww you're using. Basically,
	you'll have to modify library's Makefile to add HTSolo.c, and
	HTAccess.c to add new protocols. With lynx, I had also to modify
	LYUtils.c module to allow those URLs.
	 Some function calls have changed since libwww/2.12 (HTEscape and
	HTStreamStack), thus the OLD_LIBWWW compilation flag could be needed.
	 As a starting point, I recommend you extract
	lynx2-3/WWW/Library/Implementation from lynx-solo.tar, then look at
	CommonMakefile.diff, HTAccess.c.diff, and of course HTSolo.c.

 Any feedback will be welcome...

    -JCT-
