Creo Parametric only communicates with the server through HTTP requests. All HTTP requests, either to get an HTML page from the Windchill server, upload models, or perform a database operation through a SOAP request are being made through the embedded browser. Therefore, all of the settings that are in effect for the embedded browser, including authentication, HTTP proxy server setting, and so on apply to the Creo Parametric interaction with the server. If the Windchill server is using secure HTTP (HTTPS), then Creo Parametric also uses HTTPS.
