I am getting
< HTTP/1.1 400 Bad Request
< Content-Type: text/plain; charset=UTF-8
< Content-Length: 96
Illegal request-target: Invalid input '\', expected pchar, '/', '?' or 'EOI' (line 1, column 17)
for URLs containing \, which is ok, I'd like to have 400 going forward, but I want to change the message, so it's more user-friendly.
Seems like it happens before it gets into any of controllers.
p.s. I know there is akka.http.parsing.uri-parsing-mode = relaxed, but I don't want to do it (different message is what I want:).
Update:
sample URLs causing Illegal request-target are:
http://host.host/hello\world
http://host.host/hello{all
http://host.host/hello"all
and so on
