Related to this: URL-encoded slash in URL
I used Mehrdad Afshari's answer (wildcard route param) which works mostly! However, multiple slashes are converted to a single slash.
My route is resource/{*url}
With GET resource/abc%2fdef my controller method is called with abc/def.
With GET resource/abc%2f%2f%2f%2fdef my controller method is again called with abc/def. The extra slashes are lost.
