MQTT into web server

I have mqtt broker by ip

mqtt://xxx.xxx.xxx.xxx:8888/

I have a web site

http://mywebsite.com/

Now, I want to make like this

mqtt://mywebsite.com:8888/

If it would be like this still can:

mqtt://iot.publicwebsite.com:8888/ FORWARDFROM-> http://localhost:8888/
OR
mqtt://iot.publicwebsite.com:8888/ FORWARDFROM-> http://xxx.xxx.xxx.xxx:8888/
