I have a problem. Apache listens on a white ip and proxies all requests /ssd on
nginx that proxies requests /city-dashboard to another server with websockets.
Apache default.conf:
ProxyRequests On
ProxyPreserveHost On
<Location /test>
ProxyPass "https://127.0.0.1:443";
ProxyPassReverse "https://127.0.0.1:443";
Allow from All
Header set Connection "upgrade"
Header set Upgrade "websocket"
</Location>
nginx.conf:
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
map $http_sec_websocket_key $upgr {
"" ""; # If the Sec-Websocket-Key header is empty, send no
upgrade header
default "websocket"; # If the header is present, set Upgrade to "websocket"
}
map $http_sec_websocket_key $conn {
"" $http_connection; # If no Sec-Websocket-Key header exists, set
$conn to the incoming Connection header
default "upgrade"; # Otherwise, set $conn to upgrade
}
include /etc/nginx/conf.d/*.conf;
nginx default.conf:
location /city-dashboard {
rewrite ^/city-dashboard\/(.*)$ /$1 break;
proxy_pass http://127.0.0.1:5001;
proxy_set_header Host $host;
proxy_http_version 1.1;
proxy_set_header Upgrade $upgr;
proxy_set_header Connection "Upgrade\n\r";
proxy_set_header Sec-WebSocket-Key $http_sec_websocket_key;
proxy_read_timeout 100;
proxy_redirect off;
proxy_set_header X-Forwarded-Proto $scheme;
add_header Front-End-Https on;
}
Request headers:
GET wss://example.com:4443/test/city-dashboard/stream HTTP/1.1
Host: example.com:4443
Connection: Upgrade
Pragma: no-cache
Cache-Control: no-cache

Accept-Language: en-US,en;q=0.8
Sec-WebSocket-Key: RlhNyYNipJ1RUOU7nl4xMA==
Sec-WebSocket-Extensions: permessage-deflate; client_max_window_bits
Response headers:
HTTP/1.1 101 Switching Protocols
Server: nginx/1.8.0
Date: Sat, 22 Aug 2015 10:05:02 GMT
Sec-WebSocket-Accept: e7UKY/y5mIi8RTmhLQgFJ566dfo=
Response header lacks Upgrade and Connection, if done on site management with
nginx, I get an error 400 and websockets still does not work out. Remove the
chain Apache does not work, because it is at another organization. Can someone
with such experienced and offer some workarounds? or just have some decisions
to make it work.
