Thank you Stephen for putting it so well.
If a proxy is specified in 'set-net', Rebol
should only 'turn it on' for HTTP, FTP, and
Gopher. All other services should remain false.
This scenario would cover 90+ percent of
proxy users. It would also make distribution of
Rebol apps easier as less customization would be
required by the end user.

Most of us are aware of the work around for this behaviour but I believe
what Greg was actually suggesting is that it would be more useful for
REBOL to set up it's proxy configuration more correctly for the selected
proxy type. That is go ahead and load the defaults perhaps for cern or
socks, but insert false value assignment statements in the user.r for
schemes that are not typically handled by that proxy type. Most notably,
SMTP for example wouldn't be handled by cern or generic proxies.
I have to sympathize in this regard as I use the generic proxy type and I
either have to configure REBOL when prompted for no proxy then add the
assignments for the one scheme (HTTP) that requires the proxy or configure
the proxy settings then go back and add false assignments for all the
other schemes that can't use that proxy.
Later,
Stephen
