The Inline Frame component enables you to display a webpage within the component, allowing another HTML page to be embedded in the view.
Note that many websites will not support rendering if they're inside a frame, such as this component. Website choose to opt in to this via the x-frame-options HTTP header, which all browsers support. The x-frame-options header is designed to help prevent a class of web security attacks called Clickjacking.
Thus, if a given page returns a DENY or SAMEORIGIN value for x-frame-options, then a web browser will refuse to render the content in the iframe on your Perspective page.
