You should update to current stable (v4.3-stable) anyway, nobody has
time to support older versions.
Your approach of messing with the copy of the url you're given doesn't
sound good... the simplest way is probably to redirect the "unknown
clients" to what you want them to fetch instead.
You can see an example in minimal-http-server-tls.
