Set up a Whitelist

You create a whitelist of safe domains that Web HMI can load in to an iframe.

In Application Assembler, you can use the Whitelist_Web_Frame(GE) widget in a mashup to call any domain in that whitelist.

  1. Open the Reverse Proxy configuration file located in <install path>\ProficyWebServer\ReverseProxy\serverConfig.json.
  2. In the whitelist field, enter a list of comma-separated domain names surrounded by quotation marks. Always preface these names with https unless using a wildcard character. Use wildcards to allow the access of subdomains as well as all sources:
    "*.domain.com","https://wws.domain.*","*"
  3. Save the serverConfig.json file.
  4. Navigate to the Windows Services menu to restart the GE Proxy service.
  5. Refresh the browser clients.
