Using GeoIP Functionality in Varnish

[Ken Brownfield]

MaxMind has several different databases; the database that is the only one supported by most GeoIP "plugins" is Country, which can only map an IP to a country.  The City edition can map IPs to cities, zip codes, latitude/longitude, etc..

The plugin you mention does require the City edition, but MaxMind has a free, less accurate GeoLite City DB.  The City DB will provide country as well as the finer granularity, so for your purposes (country only) it's fine.

I do like the custom header idea, mainly because you can potentially pass the header to a backend for possible processing, but also because the conditionals are easier in VCL.

There are a lot of cool things you can do with the City DB beyond static mappings (see bind-geoip on Google Code) that would be cool to see in cosimo/varnish-geoip.
