Our reference solution for [PS1](|filename|./ps1.md) is here:
[zhttpto.rs](|filename|./zhttpto.rs).  Thanks to Kiet Tran for providing
code we used for the reference solution.

Note that our code makes an attempt to close the horrendous security
hole of allowing the server to send any requested file by removing
<tt>'/../'</tt>s from the request, but there is (at least) one major
security vulnerability remaining.  (Finding it is worth a Rust sticker.)
