That option usually sets the "home page" and not the proxy server.
For the browsers that support it (as of now, the only one that I know
that uses
it is IE5 {actually first appered in one of 4.0 versions; not sure
which;)
there is the WPAD method.
Using dhcpd 3.0+, it is possible to use the dhcp method... [thats why
when IE5
is set to autodetect all proxy settings it sends a DHCPINFORM packet to
the
dhcp server asking for more info]
the old draft is archived at
http://www.wrec.org/Drafts/draft-ietf-wrec-wpad-01.txt
(unfortunately it has expired in Dec 99; but the info in there still
works; I
cant seem to find the "final" or updated version)
in short its something like... (still... read the draft) :-)
option option-252 "http://yourwebserver.yourdomain.com/proxy.pac";;
