Bug 2002205

Description of problem:

Let's say we have 2 routes like this:
- HTTP-only route for "myapp.apps.example.com" domain and "/mypath" path
- HTTPS-edge-redirect route for "myapp.apps.example.com" and no path

In such situation, redirect is sent for any query to "myapp.apps.example.com", including "myapp.apps.example.com/mypath", so the more specific path route is not taking precedence as expected.

OpenShift release version:

4.7 (also reproduced on latest dev version)

Cluster Platform:

Any

How reproducible:

Always as per steps

Steps to Reproduce (in detail):
1. Create HTTP-only route for "myapp.apps.example.com" domain and "/mypath" path
2. Create HTTPS-edge-redirect route for "myapp.apps.example.com" and no path
3. "curl -v http://myapp.apps.example.com/mypath"


Actual results:

A redirect to https://myapp.apps.example.com/mypath

Expected results:

http://myapp.apps.example.com/mypath to serve plain http and serve whatever service is pointed by the HTTP-only more specific route.

Impact of the problem:

(check comments)

Additional info:

If we check this template fragment[1], we see that the redirect check is done before the use backend, so if there is a redirect route for which the hostname could match (even if it has less precedence than the http-only route), then the redirect is sent
