If you regularly follow this blog, you should already know a lot about Azure AD Application Proxy. I also recommend that you take a look at this presentation here: http://systemplus.gr/training/training-videos/azureadproxy/
Now we have the option to access internal resources using internal URLs even when outside our corporate network by using the My Apps Secure Sign-in Extension for Azure AD . When a user types in a familiar shorthand URL such as https://myinternalwebapp, they can be redirected to the externally resolvable URL, https://www.myinternalwebapp.systemplus.gr. This will work with any application that you have published using Azure AD Application Proxy, on any browser that also has the Access Panel browser extension installed.
You should get the latest version of the extension (supported on Edge, Chrome, and Firefox). Then, type the internal URL of the published application into the address bar. The extension will recognize that the URL has been published through Application Proxy and will redirect you to the external URL of the application.
Our users can download these extensions themselves, or admins can deploy the extension using the browser’s group policy settings. The URL redirection functionality is automatically enabled once a user logs into the extension.
To learn more about this new feature, you can read the documentation here.
Thanks for your time!
