We were escaping the URL before performing any pattern matching on it. This meant that if you sent data that URLdecoded to a "/", it would count as a "/" in the URL, potentially causing a 404. This was causing some flaky tests with some randomly-generated query parameters. Now, we keep URLs encoded while doing the pattern matching, and only afterwards do we URL decode each query parameter individually before passing them to their respective handler functions. github.com/gorilla/mux was also updated to v1.7.3 to fix a bug with URL encoding and subrouters.
