Hello nginx!

Iam trying to identify all my visitors based on their continent region,  
i want to log this info in each log entry. There is no geoip database  
for continent region so I want to map manually the countries within  
their regions.

I already have the GeoIP db loaded, and an example map for a region as  
follows:

map $geoip\_country\_code $north\_africa {  
default “”;  
##Northern Africa  
DZ 1; #“Algeria”  
EG 1; #“Egypt”  
EH 1; #“Western Sahara”  
LY 1; #“Libyan Arab Jamahiriya”  
MA 1; #“Morocco”  
SD 1; #“Sudan”  
TN 1; #“Tunisia”  
}

Would anybody kindly offer me an example of how to generate a variable I  
can use in the logging that would print “NorthAfica” if one of the  
countries in the map matched?

Thanks  
Alex

The “value” does not have to just be “1”. It could be, for example,  
“NorthAfrica”.

$north\_africa.

But it might make more sense to call it $continent\_region, and let it  
take values for the whole world.
