Current State
On this page, the uri to match is specified as /anything/* but the request is sent on /get?foo1=bar1&foo2=bar2 which returns 404: route not found as the route was defined for /anything/*

Desired State
According to the last comment APISIX will forward the request to http://httpbin.org:80/anything/foo?arg=10 and the route config, the command should be changed to:
curl -i -X GET "http://127.0.0.1:9080/anything/foo?arg=10" -H "Host: example.com"
