In the tutorial http://varnish-cache.org/wiki/GeoipUsingInlineC, you can see one way to do.
But there is another way, with no need to compile a geoip_plugin.so.
Follow these steps:
Go on http://www.maxmind.com/app/c
Download
... [More]
http://geolite.maxmind.com/download/geoip/api/c/GeoIP.tar.gz
Download the last database http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
Install GeoIp:
./configure
make
make check
make install
Update your database: GeoIp.dat (/usr/local/share/GeoIP/GeoIP.dat)
Edit your /etc/sysconfig/varnish :
add :
-p 'cc_command=exec cc -fpic -shared -Wl,-x -L/usr/include/libmemcached/memcached.h -L/usr/local/lib -lGeoIP -lmemcached -o %o %s' \
or if you don’t need memcached:
-p 'cc_command=exec cc -fpic -shared -Wl,-x -L/usr/local/lib -lGeoIP -o %o %s' \
Add the following lines in your vcl
C{
#include <GeoIP.h>
static GeoIP *gi = NULL;
const char*
get_country_code(const char* ip)
{
const char* country = NULL;
if (gi == NULL)
gi = GeoIP_new(GEOIP_STANDARD);
if (ip != NULL)
country = GeoIP_country_code_by_addr(gi, ip);
return country ? country : "Unknown";
}
}C
C{
VRT_SetHdr(sp, HDR_REQ, "\017X-Country-Code:", (*get_country_code)( VRT_IP_string(sp, VRT_r_client_ip(sp)) ), vrt_magic_string_end);
}C
Now you have the country code in a new header: X-Country-Code [Less]

There is a way to add the time taken to serve the request in the varnishncsa logs.
You must use the version 2.1.2 of Varnish.
Then apply the following patch http://varnish-cache.org/ticket/712 , you can download here.
In order to use the new
... [More]
option, launch the varnishncsa with the command line:
varnishncsa -L "%h %l %u %t \"%{VarnishR}i\" %>s %b \"%{Referer}i\" \"%{User-agent}i\" %D"
%D refer to “The time taken to serve the request, in microseconds”.
Here a list of options:
%H, Protocol version
%{Host}i
%{Referer}i
%U, URL path
%q, the query string
%U%q, URL path and query string
%{User-agent}i
%{X-Forwarded-For}i
%b, Bytes
%h (host name / IP adress)
%m, Request method
%s, Status
%t, Date and time
%u, Remote user
%D, The time taken to serve the request, in microseconds
%{X-Cache-Age}i Age of served object
I don’t know if the patch is official.
Be careful on production, i’ve some segfault:
kernel: varnishncsa[29466]: segfault at 0000000000000000 rip 000000368a2797e0 rsp 00007fff0348dbf8 error 4
