## Nginx + icomet

You can integrate icomet with nginx. If you are running you website on port ```80``` with domain ```www.test.com```. That is you visit your website home page with this url:

```
http://www.test.com/
```

Then you want to run icomet on the same server with port ```80```, for the concern of firewall issue. You can config nginx to pass request to icomet:

```
location ~ ^/icomet/.* {
	rewrite ^/icomet/(.*) /$1 break;

	proxy_read_timeout 60;
	proxy_connect_timeout 60;
	proxy_buffering off;
	proxy_pass   http://127.0.0.1:8100;
}   
```

Then, this url is used to subscribe to icomet channel xxx:

```
http://www.test.com/icomet/sub?cname=xxx
```
