Re: w3 browser ssl routines



Currently Emacs/W3 requires an external program to open SSL connections
(there is work going on to give Emacs native SSL support, but that is a
ways off).  So what SSL options are supported are entirely up to the
external program you are using.  Currently the best option is the
's_client' program from OpenSSL, and it should support all the major
flavors of SSL out there (v2, v3, TLS, etc).

The major problem with the s_client program is that even if you give it
the '-quiet' switch it doesn't shut it up completely.  The best workaround
I have found for this is to use a helper script like so:

#!/bin/sh
exec "$@" 2> /dev/null

The next major version of ssl.el in Emacs/W3 will do this for you
automatically.  But for now if you create this short script in
~/.url/exec_quietly and add the following to your ~/.emacs file:

(setq ssl-program-name (expand-file-name "~/.url/exec_quietly"))
(push "openssl" ssl-program-arguments)

Emacs/W3 does not currently support javascript - there has been some talk
about implementing it natively using Emacs Lisp, but I think the better
way to go would be an external javascript interpreter with some simple
glue code to convert from lisp to js and back again.
