Re: Last-modified фича?

$date_gmt, насколько я понимаю, не  
существует в этот момент.
это же переменная ngx_http_ssi_module
а вот почему падает воркер непонятно.

Если включаю строчку add_header, то получаю пустой ответ, даже без заголовков.

В логе вижу:

Last-modified чего должен остаться ?

Страницы или вставляемого куска (ов) ?

Или самого нового из них ?

ES> Самого нового, конечно.

модуль ngx_http_ssi имеет встроенную
переменную $date_gmt

модуль ngx_http_headers имеет директиву add_header

разве add_header Last-Modified: $date_gmt;
(или через промежуточный set) не будет
работать?

PS http://sysoev.ru/nginx/docs/

И что это даст ? Текущщее время  как Last-
modified ?
Зачем ???
