The "echo" endpoint supposedly "returns what you sent to the server", but the output includes X-Forwarded-For headers that are obviously part of your internal HTTP routing and are not part of what the client sent to the server, as well as various other headers not sent by my client. Also, the "myip" endpoint returns 2 different IP addresses. One is mine, the other is yours.
