I ran into the same issue with nginx-0.7.24 and accesskey-2.0.3. Found a Russian post and the solution is modify the "config" file of accesskey as following: -HTTP_MODULES="$HTTP_MODULES $HTTP_ACCESSKEY_MODULE" +HTTP_MODULES="$HTTP_MODULES ngx_http_accesskey_module" refer: http://www.lexa.ru/nginx-ru/msg20551.html -- Posted via http://www.ruby-forum.com/.
