Some questions to Vary Cache by Country

And one more information: I am having geoip in php and implemented this function in wordpress

function ip_info($ip = NULL, $purpose = "location", $deep_detect = TRUE) {
    $output = NULL;
    if (filter_var($ip, FILTER_VALIDATE_IP) === FALSE) {
        $ip = $_SERVER["REMOTE_ADDR"];
        if ($deep_detect) {
            if (filter_var(@$_SERVER['HTTP_X_FORWARDED_FOR'], FILTER_VALIDATE_IP))
                $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
            if (filter_var(@$_SERVER['HTTP_CLIENT_IP'], FILTER_VALIDATE_IP))
                $ip = $_SERVER['HTTP_CLIENT_IP'];
        }
    }
    $purpose    = str_replace(array("name", "\n", "\t", " ", "-", "_"), NULL, strtolower(trim($purpose)));
    $support    = array("country", "countrycode", "state", "region", "city", "location", "address");
    $continents = array(
        "AF" => "Africa",
        "AN" => "Antarctica",
        "AS" => "Asia",
        "EU" => "Europe",
        "OC" => "Australia (Oceania)",
        "NA" => "North America",
        "SA" => "South America"
    );
    if (filter_var($ip, FILTER_VALIDATE_IP) && in_array($purpose, $support)) {
        $ipdat = @json_decode(file_get_contents("https://www.geoplugin.net/json.gp?ip=" . $ip));
        if (@strlen(trim($ipdat->geoplugin_countryCode)) == 2) {
            switch ($purpose) {
                case "location":
                    $output = array(
                        "city"           => @$ipdat->geoplugin_city,
                        "state"          => @$ipdat->geoplugin_regionName,
                        "country"        => @$ipdat->geoplugin_countryName,
                        "country_code"   => @$ipdat->geoplugin_countryCode,
                        "continent"      => @$continents[strtoupper($ipdat->geoplugin_continentCode)],
                        "continent_code" => @$ipdat->geoplugin_continentCode
                    );
                    break;
                case "address":
                    $address = array($ipdat->geoplugin_countryName);
                    if (@strlen($ipdat->geoplugin_regionName) >= 1)
                        $address[] = $ipdat->geoplugin_regionName;
                    if (@strlen($ipdat->geoplugin_city) >= 1)
                        $address[] = $ipdat->geoplugin_city;
                    $output = implode(", ", array_reverse($address));
                    break;
                case "city":
                    $output = @$ipdat->geoplugin_city;
                    break;
                case "state":
                    $output = @$ipdat->geoplugin_regionName;
                    break;
                case "region":
                    $output = @$ipdat->geoplugin_regionName;
                    break;
                case "country":
                    $output = @$ipdat->geoplugin_countryName;
                    break;
                case "countrycode":
                    $output = @$ipdat->geoplugin_countryCode;
                    break;
            }
        }
    }
    return $output;
}

Would it be possible with this?

And i think final questions:
Am i right when i say “Pages that have “country code” inside always have to be set as “Private Cached URIs” ?

And would that be the solution maybe?

RewriteRule .* – [E=Cache-Control:vary=%{ENV:geoip_country_code_by_name($_SERVER[‘REMOTE_ADDR’])}}]

Tested it now for one hour with different vpn countires and it seems that my last post is the solution, but i will test further …

Now it would be only interesting how to make a cache for example italy and one for all other countrys

Hi,

Perhaps this topic will give you idea and useful information.

you may need to have a GeoIP module on your server in order to vary it on GeoLocation

Assuming you have GeoIP module on server, then use rewrite rule like this :

RewriteCond %{ENV:GEOIP_COUNTRY_CODE} IT
RewriteRule .* – [E=Cache-Control:vary=IT]

RewriteCond %{ENV:GEOIP_COUNTRY_CODE} !IT
RewriteRule .* – [E=Cache-Control:vary=not-IT]

Best regards,

Thank you i will test it. Just have seen that my solution was not as expected. WIll give you an update tomorrow.

Is it correct that all pages depending on country code have to be set as private?

Hi,

No really , if incoming visitor are guest user, they can be all public as well.

Best regards,

Tried this but doesn’t work ??

<IfModule LiteSpeed>
RewriteEngine on
RewriteRule .* – [E=Cache-Control:vary=other]
#set default vary to other
RewriteCond %{ENV:GEOIP_COUNTRY_CODE_BY_NAME} DE
RewriteRule .* – [E=Cache-Control:vary=DE]
</IfModule>

Hi,

Have you enabled Geo IP module ?

create a phpinfo page, see if you can find the geo ip variable inside of it

you should see something like this

Best regards,

Thanks for your fast response. No i cant find it.
I thought it would be there because when i made a php file with the code geoip_country_code_by_name
it worked, but all other geo_ip-codes didn’t work.

So it seems i was wrong with geoip :/

Thank you anyway for your help. Its really difficult to find a solution for my problem with countrys.

Have a nice day!

Hi,

No, the rewriterule and vary will be set before you hit PHP, and if it hits cache, PHP code won’t be executed, that’s the reason why this needs to use server level geoip module.

If you are using LiteSpeed, it should be easy to set up in few minutes

Please check this wiki

Best regards,

I am on a shared hosting. I have just opened a ticket there but i think they wont do it. Then didn’T enable crawler too yesterday .

Hi,

Then only other viable way is to enable cloudflare, it sends country in header, like the case I provided in my first reply

Best regards,

I would like to say thank you again. It seems to work now with cloudflare as you said. Will test further, especially when i update the page and so on but at the moment everything looks fine. Thanks again for helping after so many questions of me ??

Hi,

Glad to know it works for you ??

Best regards,
