Are you (Anthony) using the parametric router? The standard handling of
incoming URLs (with no router or the pattern-based router) converts spaces to
underscores. The parametric router does not.
If you're not using the parametric router, you'll find the untranslated args in
request.raw_args, a single string that you'll need to split.
If you're not using the parametric router and you want to take complete
responsibility for dealing with args (this, importantly, includes validating
them, because normal validation is bypassed), you can add your app name to
routes_apps_raw.
My recommendation: use the parametric router (see router.example.py), even if
you disable rewriting.
