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_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
