Apache .htaccess geographical redirect based on CloudFlare's geo-ip headers

.htaccess

# add as many as you need...
SetEnvIf CF-IPCountry SY RedirectSubdomain=syria
SetEnvIf CF-IPCountry AE RedirectSubdomain=uae
SetEnvIf CF-IPCountry EG RedirectSubdomain=egypt

# Only redirect if Host is not a subdomain
SetEnvIfNoCase Host ^.+\.example\.com$ !RedirectSubdomain

# Only redirect if cookie "noredirect" doesn't exist
SetEnvIfNoCase ^Cookie$ noredirect=true !RedirectSubdomain

RewriteEngine On

# Set cookie "noredirect"
RewriteCond %{ENV:RedirectSubdomain} .+
RewriteRule .* - [co=noredirect:true:.example.com:7200:/] #7200 minutes

# Redirect to subdomain
RewriteCond %{ENV:RedirectSubdomain} .+
RewriteRule ^ http://%{ENV:RedirectSubdomain}.example.com%{REQUEST_URI} [L,R]

hello mate, im trying to do something similar. Instead of subdomains i want to redirect users to the same url with the /?lang=XX parameter

do you know how can i do it ?
