Look at the URL redirector: https://marketplace.mendix.com/link/component/113
You can redirect a user to an external webpage.
In addition to Ronald’s suggestion, I have a couple of other alternative approaches that may be of use depending on your requirements.
If you want to download the content and serve it as if it’s within the Mendix application, then you could look at call using a “Call REST” action in a microflow to download the content, and then return the response as a String that you can store in an entity and show on page.
Alternatively, you could use an iFrame to just render the external content directly. You can use an HTMLSnippet widget from the Marketplace to do this.
Hope this helps.
here is the microflow setup, does this look right…
