Right now [questions tagged `soapi.cs`][1] returns a HTTP status code 404 (for various HTTP clients) while [questions tagged `soapi.js`][2] does not.

Interestingly though, `soapi.cs` seems to work just fine in other places, e.g. [Newest `soapi.cs` questions][3] returns the desired result, and so does [Stats on `soapi.cs`][4]. That is, as soon as (sort) parameters are included the route seems to work as expected, but not without?

What's the magic difference here?
