[rt-users] lighttpd + FastCGI + RT - Broken CSS / Menu Items Dont Work

After over a day trying to get lighttpd + FastCGI working.. I FINALLY
found the last major problem.
The mason handler that is provided with RT 3.8.6(mason_handler.fcgi) is
*NOT COMPATIBLE* with lighttpd. It works perfectly fine for Apache. The
numerous mason_lighttpd_handler.fcgi scripts that are found online all
have a code error in them that causes lighttpd to crash. So they are
invalid as well. (Easily verifiable and reproducable)
It appears the underlying problem with the built-in mason_handler.fcgi
is that the CGI::Fast call is not able to properly deduce the current
URL that is being pulled up. This value should be stored into
$cgi->path_info.
I found an article from 2006(yes, I said, 2006) where someone posted a
diff between the built-in handler and what he found finally worked. I
applied the changes to my handler, and after a quick restart of lighttpd
it started showing my RT instance properly with colors, CSS, and all
menu items work.
It appears that this problem/bug has persisted for at least three years.
This may explain why there is such little information on lighttpd +
FastCGI and getting it to work properly. I'm posting the corrected
handler here, and will post it as a bug as well so hopefully Best
Practical can provide the lighttpd handler in future releases of RT as well.
In case anyone stumbles onto this thread in the future, here is my
complete mason handler code:
