limited access

[birdman911]

I need script for limiting access by zip code. if zip code is good then go to ecommerece if it matches a bad zip code (my choice) then goes to default page for more info. Like this I type in 95610 thats a bad it goes to default page I type in 88455 a good one it goes to my online store.
The purpose its to open my online store only in little chunks.
thanks I don't even mind buying a program to do that if I have to. I use Dreamweaver MX

thanks

Unless you have only a few 'bad' zipcodes, this is done server-side. Javascript is client-side.
