Спасибо. По задумке то что надо. Пробую на стабильной версии 1.4.2:
location / {
eval $var {
set $memcached_key "$request_uri";
memcached_pass localhost:11211;
}
proxy_pass $var;
}
Получаю в логах:
2013/09/23 16:24:49 [debug] 24218#0: *1 test location: "/"
2013/09/23 16:24:49 [debug] 24218#0: *1 test location: "eval_7274000"
2013/09/23 16:24:49 [debug] 24218#0: *1 using configuration "/"
Вторая строчка это subrequest для перехода по значению memcached, однако дальше
