We have an Azure App Service and an on-prem application. Both must be accessed within a single domain. For instance, www.domain.com goes to App Service while www.domain.com/login goes to the on-prem app. The problem: Both are .NET applications and may have the same resources names. I.e. /assets/main.css exists in both. How can I set up a layer that redirects the request to the proper resource/server, depending on which server is responding to the first request? Which Azure tool would you suggest for? Thanks in advance.
