I am looking to implement a very basic country limiting on my site based on the Maxmind geoip database (free version). Basically, I want to limit all users of the site to one country only. What I'm wondering is: is there any performance gain using the Apache API versus the PHP API?
I want to be able to use the country code for more than just a simple redirect (display messages in different languages, etc.), so that's why I'm leaning toward PHP, but my number one concern is the impact on performance.
Thanks for any advice.
