I've used the search to find this but no luck.

I'm looking for a script that will detect a visitors location when visiting the site and redirect them to a corresponding section.

Cannot be done with HTML and how exactly do you think a script is going to find the users "zipcode"???

Thanks for the response, Chris.
What can it be done in, and what is the best way to detect location?

Ask the user! Store the info they give you in a cookie or a session, then tailor the pages based on that.

But don't make it obligatory. You have to consider that:

They may NOT be searching for themselves.
They may be planning a holiday (vacation).
"They" might be a search engine.

What you're interested in using is what's called 'geolocation' info. You'll need to either utilize server-side back-end coding to take the user IP, search your database (that contains IP block to geographic location) to estimate the zip code.
An alternative is to search the web for 'geolocation services' as I seem to recall a few websites that allowed webmasters to make a remote call to their geo-tables to determine the geographic location of the visiting customer.
This does assume the user is visiting from their actual IP, and not a proxy :-)

Hi, I am not sure if this is what you want, but they had implement the auto redirection based on the visitor's IP.
