'GET' delete trailing slash '/' after responce

[sergeos]

If you write in URL link with trailing slash, like:
.../api/models/
and then, adding some parameters on Parameters tab, like
year: 1987
then, Requester delete trailing slash from URL and return bad request.
So, i need this request:
...api/models/?year=1987
and, Responder make string with error:
...api/models?year=1987
