     #As part of the security improvements, Exalate 5.5.0 validates the origin header
     #that the browser is sending upon every request to Exalate.
     #In order to validate the origin header, Exalate needs to know what is the URL 
     #leading to it.
     #When deploying Exalate to Docker one needs to put an environment variable NODE_SELF_URL.
     #Example:
     # When you deploy Exalate onto a server, you configure a DNS rule such that 
     #whenever people navigate to foo.com, they reach your server's Exalate. 
     #You set up SSL so that https://foo.com leads to your Exalate on your server.
     #Now you need to set environment variable 

     - NODE_SELF_URL=https://foo.com 

     #for your Exalate docker container.
