Webflow doesn't have a specific feature that allows users to specify a fully qualified URL in the "Redirect to Page" field within the Webflow platform.
However, there are workarounds that you can use to achieve the desired functionality. One approach is to utilize custom code or JavaScript to dynamically redirect users to a specific URL.
To implement this, you can add a custom code component to your Webflow project and include a JavaScript script that will handle the redirect functionality. Within the script, you can define the specific URL you want to redirect users to.
Here's an example of a JavaScript script that can be used to redirect users to a specific URL:
```javascript
```
Replace `"https://www.example.com"` with the fully qualified URL that you want to redirect users to. You can add this script to the custom code component and place it on the page from where you want to redirect users.
Remember to test the redirect thoroughly before deploying it to ensure it works as expected.
Please note that my information may not be up to date, as Webflow regularly introduces new features and updates to their platform. It's always a good idea to consult Webflow's official documentation or community forums for the most recent information and updates on features and functionalities.
