tux name based virtual hosting question

hi,
i have tux 2.0.26 set up and running (and apache as dynamic secondary server, albeit unused at the moment). only one site on it now.
i want to add some more sites to this box, preferably sharing the same IP. i have searched google and redhat, now onto the
forums....

i found http://people.redhat.com/mingo/TUX-patches/2.1-docs/virtual-hosting.html  that is the closest i have found to what i need.
however it doesn't have an example of syntax. how do i enter these tunable variables into /etc/sysctl.conf?

for example: (from the above link)
===================snip================

There are three tunables that deal with virtual hosting:


  a.. virtual_server - Valid values are 0, 1, 2, or 3.

  b.. mass_hosting_hash - Valid values are 0, 1, 2, or 3.

  c.. strip_host_tail - Value must be an integer.

These three tunables depend on each other, and the strip_host_tail tunable is only used if host based virtual serving is enabled.
Otherwise, it is ignored.

virtual_server
If the value is set to 0, virtual hosting is disabled:

http://www.example.com/a.html => $DOCROOT/a.html


If the value is set to 1, host-based virtual hosting is enabled:

http://www.some.site.com/a.html => $DOCROOT/some.site.com/a.ht?ml


=========snip==================
so first i make a user directory in the doc root (e.g. var/www/html/newsite)
so in /etc/sysctl.conf  would i put:

virtual_server = 1
http://www.newsite.com/*.html => $DOCROOT/newsite.com/*.html

or simply by virtue of using names in the entry does it assume mode 1?

must i specify each html page as an entry (as in /a.html above) or will the wildcard (*)in the above work?

and is virtual host set to (equal sign) 1 or (=>) or what?

and don't i have to label the section "virtual host" (or #virtual_host)?

i'd really just like to see an example of /etc/sysctl.conf from a working setup (fake names/ IP's of course)
then i would feel safe trying it on the now live and critical server.
i have no other box with tux/apache setup to test so i a bit leery. new to tux in june.
thanks for any help.
