This must have been discussed before but I am new to nginx  
and this forum.

I am upgrading to 1.4 to use its websocket proxy feature.  
Say I have a websocket server running at port 81, so I want  
to forward all websocket packets to port 81, and process  
the rest at port 80.

Somehow the following conf doesn’t work, anything missing?

server {  
listen [::]:80 ipv6only=off;

```
    location / {
        regular_http_processing_directive;

        if ($http_upgrade = "websocket") {
            proxy_pass http://localhost:81;
        }

        proxy_http_version 1.1;
        proxy_set_header Upgrade websocket;
        proxy_set_header Connection upgrade;
    }

```

}

At the http level:

map $http\_upgrade $connection\_upgrade {  
default upgrade;  
‘’ close;  
}

map $connection\_upgrade $proxy\_upstream\_port {  
upgrade 81;  
close 80;  
}

Then at the location do:

location / {  
proxy\_http\_version 1.1;  
proxy\_set\_header Upgrade $http\_upgrade;  
proxy\_set\_header Connection $connection\_upgrade;  
proxy\_pass [http://localhost](http://localhost):$proxy\_upstream\_port;  
}

Thanks for the recipe.

Just tried and now I am not able to get regular  
HTTP working on port 80.

Has anybody ever got nginx websocket proxy working?

Thanks,
