External Content
External Content component can be used to show content from other webpages, such as from Microsoft Sharepoint or other content management systems, enabling to integrate multiple web applications into the single UI. The External Content component uses the HTML iframe element to embed the content.
By default, only websites from the same origin than the QPR ProcessAnalyzer server can be embedded. This is due to the Content security policy HTTP header (more information: Security Hardening).
Settings
Following properties can be set on the Properties tab:
- Name: Name of the External Content component.
- Description: Description for the External Content component.
- External Content URL: The URL of the external page you want to embed. You can also use a relative path (e.g. "/examples/test.html"), if the page you want to embed is accessible by the same protocol, host, and port.
Passing Variables in Url
You can pass context variable values in the iframe url using the variable tags. Example:
http(s)://SERVERNAME/ExternalPresentationObjects/ExternalPresentationObject1#variable1=<#variable1>&variable2=<#variable2>
Web Browser Security Considerations
Some websites prevent themselves to be embedded into other websites using iframe. In those cases, the component will be left blank (in Chrome and Firefox) or there may be an error message "This content cannot be displayed in a frame". The way to workaround the issue is to have X-Frame-Options HTTP response header changed in the embedded website (more information: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options).
