upstream 长连接问题

soaercom

location /vbs {

internal;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_http_version 1.1;

proxy_set_header Connection "";

proxy_pass http://ka/query;

}

location /vbs {

internal;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_pass http://ka/query;

proxy_http_version 1.1;

proxy_set_header Connection "";

}

upstream ka {

server 0.0.0.0;

balancer_by_lua_file /home/doop/balance.lua;

keepalive 150;

}

我使用ngx.location.capture_multi() 函数访问/nbs，但是打印出来的header里面怎么都没有看到Connection: keep-alive，

只有"header":{"Content-Type":"application\/json"}，不知道怎么回事，是否有其他办法测试用capture_multi发出的连接请求是长连接呢？上面两种配置都试了。capture_multi访问后的结果里面没有Connection: keep-alive。大家谁遇到过这样的问题请教一下

用curl -i url 能打出来Connection: keep-alive

Content-Type: application/json

Transfer-Encoding: chunked

Connection: keep-alive

Hello

ngx.location.capture 和 capture_multi 并不会改当前请求的 header 信息

你这里最好是用 tcpdump 来分析
