Redirect depending on source ip address

Hi all.

I'm looking for a solution to do something like this (cause of firewall
restrictions):

if a user comes into a specific virtual server in my apache web server from
an ip 10.x.x.x it should be redirected to

www.mywebsite.it:8081

if it comes from an ip 192.168.168.x it should be redirected to
192.168.168.111

if it comes from everywere else it shoud be redirected to

www.mywebsite.it:8082

Is it possible?

Befor using linux i've had a iis win2k server and with a simple .asp page i
did it, but now it does not work and i don't want to use asp anymore

Tks
