Hi there and thank you for reaching out to the Q & A community.
Please correct me if I'm wrong.
From your description it sounds like the first app running on 443 is trying to redirect to the 2nd app running on port 449.
If this is it the case then you may be able to get around this by using Link translation.
Steps to use link translation:
- Ensure each application is published using app proxy. App 1 will have internal and external urls going to 443. https://mydomain.we.net/myapp02/ App 2 will have internal url going to https://mydomain.we.net:449/myapp02/ and external going to https://mydomain.we.net/
- In your app proxy settings please ensure that translate urls in headers and body are checked.
If the steps above were able to help you please accept this answer or if my understanding of your scenario is incorrect please let me know how you have configured both applications through app proxy.
How are you accessing the application working on 449? is it directly through app proxy or is the first app redirecting the 2nd app?
