Plack::Middleware::RearrangeHeaders sorts \s-1HTTP\s0 headers based on \*(L"Good Practice\*(R" i.e.:
.PP

to work around buggy clients like very old \s-1MSIE\s0 or broken \s-1HTTP\s0 proxy
servers. Most clients today don't (and shouldn't) care about \s-1HTTP\s0
header order but if you're too pedantic or have some environments
where you need to deal with buggy clients like above, this might be
useful.
