How can I use ngx_http_geoip to query a parameter value instead of the default client IP address?

thanks,

Alternatively, is there a "openresty" way to query a GeoIP database for a given parameter value or will using lua-geoip be sufficient?

thank you

Yes, you're free to use Lua binding for the geoip library for maximum
flexibility. Better use a binding based on LuaJIT FFI such that the
surrounding Lua code can be JIT compiled by LuaJIT. Another thing to
note is to cache the loaded database and you can also share it by
initializing it in init_by_lua and let the operating system's
Copy-On-Write (COW) feature take care of the rest among all the nginx
worker processes.

Hi Agentzh,

Thanks for your advice. Googling around did not find a Lua GeoIP library with LuaJIT FFI bindings. Are you familiar with such a library?

Great advice.

No. But you can use LuaJIT FFI to create such bindings yourself. It
should be quite easy if you're familiar with C. See
