Usage behind Apache Proxy about ympd

[ajs124]

I have a proxy setup with nginx, which works fine. How about using the firefox devtools or firebug to debug the issue? The network tab (Netzwerkanalyse, the rightmost tab) in the devtools shows you the requests it sends and the responses from the server.

Server logs might also be helpful.

I would prefere to use Apache, because there is already one running.
When using firefox network analytics, it shows that there is always the same request going out, but is never answered:

GET http://music/
Host: music
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Sec-WebSocket-Version: 13
Origin: http://music
Sec-WebSocket-Key: xI8MWwDX2Y7Buw+KAQBbmQ==
Connection: keep-alive, Upgrade
Pragma: no-cache
Cache-Control: no-cache
Upgrade: websocket

Is there probably somethign wrong with the proxy? Mpd runs on the same maschine.

Hi,

you need to proxy the websocket request:

http://httpd.apache.org/docs/2.4/mod/mod_proxy_wstunnel.html

[laclaro]

ajs124, could you post your nginx setup? I want to redirect http://mydomain.com:80/ympd to http://localhost:8080 or better https://mydomain.com:443/ympd to http://localhost:8080. Without ssl I do it like this:

location /ympd/ {
rewrite /ympd/(.*) /$1 break;
proxy_pass http://127.0.0.1:8080;
# websocket handling does not help at all
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
}

But then I experience the problem, that there cannot be established a connection to mpd. Adding the websockets directives to this config did not help yet.

best regards
Henning

I'm also interested in an apache config... This doesn't work:

    <IfModule mod_proxy.c>
        <IfModule mod_proxy_http.c>
            ProxyVia On
            ProxyRequests Off
            ProxyPass / http://localhost:8080/
            ProxyPassReverse / http://localhost:8080/
            ProxyPass "/ws/"  "ws://localhost:8080/ws/"
            ProxyPreserveHost Off
            <Proxy *>
                Options FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
                Require all granted
            </Proxy>
            <Location />
                Order allow,deny
                Allow from all
                Require all granted
            </Location>
        </IfModule>
    </IfModule>

Hi,

Below that does work with ympd (and possibly other applications based on WebSockets):
k-rpi is a music server with mpd + ympd, hidden behind NAT

<VirtualHost *:8080>
        ServerName k-rpi.hostname
        ProxyRequests Off
        ProxyPass          / ws://k-rpi/
</VirtualHost>

<Proxy http://k-rpi/*>
        Order deny,allow
        Allow from all
</Proxy>

This also works:

<Location /ympd>
RewriteEngine On
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule /ympd/(.) ws://localhost:8082/$1 [P,L]
RewriteCond %{HTTP:Upgrade} !=websocket [NC]
RewriteRule /ympd/(.) http://localhost:8082/$1 [P,L]
ProxyPassReverse http://localhost:8082
