Thanks to Ilya Novikov. *) Feature: the "If-Range" request header line support. Thanks to Alexander V. Inyukhin. *) Bugfix: in HTTPS mode requests might fail with the "bad write retry" error; bug appeared in 0.5.13. *) Bugfix: the STARTTLS in SMTP mode did not work. Thanks to Oleg Motienko. *) Bugfix: large_client_header_buffers did not freed before going to keep-alive state. Thanks to Olexander Shtepa. *) Bugfix: the "limit_rate" directive did not allow to use full throughput, even if limit value was very high. *) Bugfix: the $status variable was equal to 0 if a proxied server returned response in HTTP/0.9 version. *) Bugfix: if the "?" character was in a "error_page" directive, then it was escaped in a proxied request; bug appeared in 0.5.32.

# this script converts CSV geoip database (free download at http://www.maxmind.com/app/geoip_country)
# to format, suitable for use with nginx_http_geo module (http://sysoev.ru/nginx)
#
# for example, line with ip range
#
#   "62.16.68.0","62.16.127.255","1041253376","1041268735","RU","Russian Federation"
#
# will be converted to four subnetworks:
#
#   62.16.68.0/22 RU;
#   62.16.72.0/21 RU;
#   62.16.80.0/20 RU;
