.SH DESCRIPTION
.IX Header "DESCRIPTION"
Plack::Middleware::RearrangeHeaders sorts HTTP headers based on "Good Practice" i.e.:
.PP
.Vb 3
\&  # "Good Practice" order of HTTP message headers:
\&  #    \- Response\-Headers
\&  #    \- Entity\-Headers
.Ve
.PP
to work around buggy clients like very old MSIE or broken HTTP proxy
servers. Most clients today don't (and shouldn't) care about HTTP
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.
