Static and Dynamic content URL

Question

I am trying to display the appian document inline by using a!documentViewerField().W hile testing got the error "Missing system configuration". 
 I Would like to understand what needs to be passed for following properties in custom.properties file, in order to make it work. 
 conf.suite.STATIC_SERVER_AND_PORT 
 conf.suite.DYNAMIC_SERVER_AND_PORT 
 Already referred documentation and left with no help. 
 Any thoughts on this will be appreciated! 
 
 Thanks, 
 Nishanth

Hi erickp 
 Below is the reason why Appian doesn't support sub domain for these requirements as documented here : 
 User-uploaded files and third-party extensions may contain JavaScript code and/or set cookies that pose a potential security risk to your users. Web browsers have built-in security measures that prevent different sources of web content from interacting in dangerous ways. These protections are only applied when content is served from separate domains (not separate subdomains). Appian's URL validation mirrors this browser domain comparison behavior to ensure that your users are safe.
