We have setup Lightstreamer on two seperate servers.
Machine A hosts the website and responds to  
http://company.comand 
http://www.company.com 
Machine B Hosts lightstreamer and responds to push.company.com
When I visit  
http://company.comin Internet Explorer I get permission denied errors and the engine doesn't bind.  If I visit 
www.company.com  this problem does not occur.
It works using both URLs in Firefox.
Is this a security limitation in Internet Explorer or there a setting I need to change for IE?
