Всем привет!
Столкнулся с неожиданной проблемой. Если включен proxy_cache и используется
ssi, curl часто выдает ошибку
* Received problem 3 in the chunky parser
* Closing connection #0
curl: (56) Received problem 3 in the chunky parser
и в error.log:
2014/03/05 16:33:55 [info] 31373#0: *525 client prematurely closed
connection while sending to client, client: 1.1.1.1, server: host.ru,
request: "GET / HTTP/1.1", subrequest: "/includes/lists/tabloid", upstream:
"http://127.0.0.1:9030/includes/lists/tabloid";, host: "host.ru"
Все начинает правильно работать, при следующих условиях:
1. ssi off и тогда nginx начинает передавать curl заголовок Content-Lenght
2. proxy_cache не используется и ssi on
Конфиг:
ssi on;
gzip_static on;
keepalive_requests 20;
location ~ ^/includes {
include /etc/nginx/conf/access.conf;
proxy_cache some-cache;
proxy_cache_valid 200 302 301 304 10s;
proxy_cache_key "$request_method|$host|$uri";
proxy_hide_header "Set-Cookie";
proxy_ignore_headers "Cache-Control" "Expires";
proxy_cache_use_stale error timeout invalid_header updating
http_500 http_502 http_503;
proxy_cache_lock on;
proxy_http_version 1.1;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For
$proxy_add_x_forwarded_for;
proxy_set_header Accept text/html;
proxy_set_header Host host.ru;
proxy_pass http://localhost:9030;
}
location / {
proxy_cache some-cache;
proxy_cache_valid 200 302 301 304 30s;
proxy_cache_key "$request_method|$host|$uri";
proxy_hide_header "Set-Cookie";

$proxy_add_x_forwarded_for;
proxy_set_header Accept text/html;
proxy_set_header Host host.ru;
proxy_pass http://localhost:9030;
}
