triPOS supports requests from cross-origin domains. By default, CORS Support is disabled and can be edited inside tripos.config using the property corsAllowedOrigins.
To allow all domains, set corsAllowedOrigins to *.
Here is an example of CORS Support only for Vantiv.com:
<corsAllowedOrigins>http://vantiv.com</corsAllowedOrigins>
Here is an example of CORS Support for Vantiv.com and Elementps.com:
<corsAllowedOrigins>http://vantiv.com,http://google.com</corsAllowedOrigins>
Here is an example of CORS Support for all domains:
<corsAllowedOrigins>*</corsAllowedOrigins>
