ASP help???

I need help in creating a asp page that will check the users screen resolution and redirect it to a specific html page based on the resolution. I believe this can be accomplished using asp and I this script on the web to check the resolution:
response.write(request.servervariables("http_ua_pi xels")
but I need help incorporating this with the redirect and i also do not believe netscape will return the resolution with this code. I appreciate any help anyone can give me.
Thanks in advance!
