I am running Links SQL at a well established site in a small niche area and recently decided to change my domain name. I would like to redirect all the traffic from my old URL to the new one. Since I am not very well acquainted with Apache modules, I would like to know what's the best way to redirect requests like

www.olddomain.com/cgi-bin/jump.cgi?ID=123 to
www.newdomain.com/cgi-bin/jump.cgi?ID=123

I have read the Apache docs about mod_alias and mod_rewrite (both are available on my server), but I am still unsure of how to proceed. Any help is appreciated!
