http://www.fi.muni.cz/~kas/mrtg-rrd/ умеет FCGI
но пока nginx воспринимает слешь как переход каталога он просто незапускает
скрипт.
А если запускать скрипт через встроенный перл ? Можно ли получить большую
производительность ?

=======================================================================
Строки из перл скрипта которые меняли переменные окружения убрал и добавил
демонизацию и
$EUID = "65534"; $EGID = "65534"; чтоб безопасность хоть как то увеличить
...
Если кто то подскажет как реализовать эту кнструкцию
location ~ /index.cgi/ {
if ($fastcgi_script_name ~ (.*/index.cgi)/.*$) {
set $valid_fastcgi_script_name $1;
}
с проверкой файла и вложенным циклом, чтобы было для всех случаев буду
признателен.
