DUE TO PERSONAL CIRCUMSTANCES I AM NO LONGER ABLE TO DEVELOP OR SUPPORT THIS PLUGIN. IF YOU ARE INTERESTED IN ADOPTING THIS PLUGIN SEE https://developer.wordpress.org/plugins/wordpress-org/take-over-an-existing-plugin/
Solves wrong country content for visitor Geo-Location issues. Enables Comet Cache to display the correct page and widget content for a visitor’s country.
Bonus also makes Cookie Notice work correctly with Comet Cache (whether using country/EU geolocation or not).
If you need country caching with other caching plugins then see “Advice” below.
This plugin adds an extension to Comet Cache enabling it to create separate snapshots (cache) for each page based on country location.
Extra caching can be restricted to specific countries and/or a group of countries. E.g. if you are based in the US but show different content to Canadian,Mexican & EU country visitors, you can set separate caching for CA & MX visitors + single group cache for EU visitors; the remainder of your visitors will standard cache (“US”) content.
It works on normal WordPress and on Multisite (see FAQ).
Comet Cache is designed to work with add-on scripts and should work seamlessly with this plugin.
Identification of visitor country for caching
Via Cloudflare or Maxmind. (this product includes GeoLite2 data created by MaxMind, available from http://www.maxmind.com ) It is also possible to connect a different GeoLocation sytem of your choice (see documentation).
If you use Cloudflare and have “switched on” their GeoLocation option ( see Cloudflare’s instructions ) then it will be used to identify visitor country. If not, then the Maxmind Country Database will be used.
Updating (If not using Cloudflare for country) The installed Maxmind Country/IP data file will lose accuracy over time. To automate a monthly update of this file, install and enable the Category Country Aware (CCA) plugin (Country Caching and the Cataegory Country Aware (CCA) plugins use the same Maxmind data file in the same folder and the CCA plugin includes code for its update). The CCA plugin has many other features and functionality you may find useful. Alternatively you can manually update (FAQ below).
Additional Info and support
Don’t use ANY Caching plugin UNLESS you know how to use an FTP program (e.g. Filezilla).
Support forums show that Caching plugins including Comet Cache can result in “white screen” problems for some users; the only solution may be to delete files using FTP/Cpanel or OS command line.
The Country Caching plugin deletes files on deactivation/delete, but in “white screen” situations you may have to resort to “manual” deletion – see FAQ for instructions.
WP Super Cache: is also designed to work with “add-ons” and an equivalent of this plugin is available in the WordPress repository.
W3 Total Cache does not currently provide a suitable hook for plugin country caching. Others have requested this facility.

The easiest way is direct from your WP Dashboard like any other widget:
Once installed go to: “Dashboard->Country Caching”. Check the “Enable CC Country Caching add-on” box, and save settings.
If you want automatic “3 weekly” update of Maxmind Country->IP range data then also install the Category Country Aware plugin (here on WordPress.Org).
Where can I find support/additional documentation
Support questions should be posted on WordPress.Org
Additional documentation is provided at http://wptest.means.us.com/quick-cache-and-geoip-enable-caching-by-pagevisitor-country-instead-of-just-page/
How do I know its working
See these checks.
How do I keep the Maxmind country/IP range data up to date
Automatically: install the Category Country Aware plugin from WordPress.Org and enable its settings; it will update your Maxmind data every “month”.
Manually: monthly/whatever; download “GeoLite2-Country.tar.gz” from Maxmind and extract the file “GeoLite2-Country.mmdb” and upload it to your servers “/wp-content/cca_maxmind_data/” directory.
Will it work on Multisites
Yes, it will be the same for all blogs (you can’t have it on for Blog A, and off for Blog B).
On MultiSites, the Country Caching settings menu will be visible on the Network Admin Dashboard (only).
How do I stop/remove Country Caching
Deactivating the plugin will remove the Caching Extension. Then clear Comet’s cache (Dashboard->Comet Cache->Clear)
If all else fails:
- Log into your site via FTP; e.g. with CoreFTP or FileZilla.
- Delete this file: /wp-content/ac-plugins/cca_qc_geoip_plugin.php
- Delete this directory: /wp-content/plugins/country-caching-extension/
- Then via your WordPress Admin: Dashboard->QuickCache->Clear

Fix for Cookie Notice, to make it work correctly with Comet Cache (whether or not you are using geolocation or CCA to restrict CN to EU visitors)
(if your site is not using Cloudflare) Maxmind GeoLite2 will be used for country look-up instead of Maxmind Legacy (no longer updated by Maxmind).
Connector also provided to allow use other GeoIP look-up system in place of CF/Maxmind country lite.
Added checking of additional server variables for visitor’s IP Address.
Fixed display bug on “Support Tab” – extension info will now display even if Caching has not been enabled in Comet Cache.
Support Tabs “Display GeoIP data” now displays values of the server’s visitor IP variables
Maxmind data files are now auto installed (when you first enable Country Caching) in a shared directory for use by other plugins.
The data files are provided by Maxmind under Creative Commons license, but the WordPress.org repository requires all files stored there should be licensed under GPL. The Plugin has been altered to comply.
