Allow status requests to ignore trailing path

[WorkProg]

I want to test a services' error behavior by having it get back 500 status codes on an external web request.

The issue is, that it will append additional path to the configured URL, so when I set it to http://httpbin.org/status/500 the actual request is http://httpbin.org/status/500/more/stuff resulting in a 404 instead of the 500.

This is somewhat of a continuation of #315.
