Incorrect routing when the query parameter is in the configuration

[Burgyn]

Hi guys.

I discovered strange and different routing behavior between versions 22.0.1 and 23.0.0.

Expected Behavior

In version 22.0.1 the routing works well as expected.
We have the following configuration:

{
    "DownstreamPathTemplate": "/{tenantId}/products?{everything}",
    "UpstreamPathTemplate": "/{tenantId}/products?{everything}",
    "UpstreamHttpMethod": [ "Get" ]
},
{
    "DownstreamPathTemplate": "/{tenantId}/products/{everything}",
    "UpstreamPathTemplate": "/{tenantId}/products/{everything}",
    "UpstreamHttpMethod": [ "Get" ]
},

When I call a request

GET localhost/1/products/1

then the correct route "/{tenantId}/products/{everything}" is selected.

Actual Behavior

In version 23.0.0 the "DownstreamPathTemplate":"/{tenantId}/products?{everything}" path is chosen for some reason, which is not correct.

Specifications

• Version: >23.0.0

Maybe this PR? #748

Any idea for a quick fix on my part?
Thank you very much.

Eliminate the initial redundant route as it is inherently included in the subsequent Catch All route.

It should be one route only

{
    "DownstreamPathTemplate": "/{tenantId}/products/{everything}", // all query strings are included
    "UpstreamPathTemplate": "/{tenantId}/products/{everything}",
    "UpstreamHttpMethod": [ "Get" ]
},

Also, note that if no Priority is defined, then the first matching route prevails! This explains the odd behavior observed.
