I have a url www.abc.com
I would like to redirect this url to an exisitng url www.xyz.com/a/b hosted on a iPlanet webserver
However upon simple DNS redirection - I got an error - 500 "Unable to process request"
What change needs to be done on iPlanet web server to allow redirect requests from other URLS
and how can I forward the request to a sub directory on the web server /a/b
