Re: Securing web site with redundancy ?

["Web Manager" <jburke () aea11 k12 ia us>]

We've done this on two layers.  We run WebStar for our web server and it
allows you to run Apache in the background.  Same default Documents
directory for both and voila, if Web* crashes Apache picks it up on the same
machine.  Likewise, by running mod_proxy on both web servers with identical
WebStar/Apache setup we can load fail over with little difficulty.

I've never tried to do this with any other application other than WebStar,
you *shouldn't* be able to run 2 services on :80 like that but it works and
does so consistently across multiple machines.  Apache has to start first
and then WebStar has to 'take over' :80.  IF WebStar fails, Apache picks up
without a hitch, I've clocked 3 second switch overs.
