Hi Dario,

Sorry that was just a typo - I was removing the name of actual site that I'm working on. So for this case, I've tried to keep it generic to mysite.com.
Just to clarify, I use the hosts file for testing locally (as the site is currently live, but without the new functionality I'm currently working on).

When we go live with the new functionality, there shouldn't be a problem with using:

Site: mysite.com
Web: www.mysite.com
Lightstreamer: lightstreamer.mysite.com

The problem arises when we include the environment (local, uat, stage) and "www" in the URL, such as local.www.mysite.com.

Is there something else I need to do for this to work?

Many Thanks,

C
