my two cents on ultraseek:

we have an installation of ultraseek on our campus, and i've had more bad
experiences with it than good. i won't argue for the search capabilities,
since i'm fairly certain that the infoseek people are paid to make it

however, the problem i've run into probably pertains to you. our web
server has four alias (all of which point to the same "site"). when the
server was first set up, it indexed the site by the canonical name (which
wasn't what we wanted). after a while, it switched everything so that all
search hits pointed to the alias i had originally wanted. then after a few
more weeks, it realized my web server had another alias, and switched to
that. a few weeks ago, i got two more aliases, and all ready ultraseek is
treating all of my pages as being on one of the NEW aliases!!!.

in any event, ultraseek has the capability to remove duplicate pages from
its index, however you never know what alias it's going to index your
machine as. if it finds an alias to your machine, it might just reindex
everything, throw out the old duplicate files, and keep cycling through

my personal solution (which i implemented too late) is to have two
separate of virtual hosts. one virtual host will be what you want to
present to the outside world, and what you want pages to be indexed as.

the second virtual host container will contain all your serveralias
directives to respond to all the aliases, and will have the same
configuration, in general. HOWEVER, the important difference is that it
should have:

Alias /robots.txt /wwwfake/robots.txt

and this fake robots.txt should be EXTREMELY restrictive. so basically,
when any spider tries to access your machine by one of the aliases, it
will be disallowed by the robots.txt. when it accesses your machine by the
intended machinename, it'll get a real robots.txt file.

i'm not sure if this will work for you, in that you might not be running
unix web-servers. i'm not sure if MS IIS has any sort of support for this.
(specifically, having a different robots.txt when the machine is
referenced by a different name.
