Other members of the list can tell your experience with zen and http services. For zen is indifferent that you use iis, apache or other application, if this works over tcp protocol Feel free for test zen with your IIS configuration and report us your doubts > > > I have run Linux-HA in the past but only on a segregated network and only > for SSH so the traffic was very minimal and thus I wouldn’t have seen any > issues like potentially here on the http cluster. > > > > Any comments/suggestions ? > > > > Thanks, > > > > Dave > > ------------------------------------------------------------------------------ > All of the data generated in your IT infrastructure is seriously valuable. > Why?
