1 Lighttpd apparently sets REDIRECT_STATUS=200 for the server.error-handler-404 page. This breaks the 404 plugin which checks this variable for 404 before processing the URI. It also doesn't seem to set REDIRECT_URL.
3 I was able to fix my server to check the REQUEST_URI for ikiwiki.cgi and to continue processing if it was not found, passing $ENV{SEVER_NAME} . $ENV{REQUEST_URI} as the first parameter to cgi_page_from_404. However, my perl is terrible and I just made it work rather than figuring out exactly what to do to get it to work on both lighttpd and apache.
5 This is with lighttpd 1.4.19 on Debian.

15 >> As I said, I got it working for me, but somebody who knows perl should probably look at it with the aim of making it work for everyone.
16 >> I considered having lighttpd construct a proper url for the 404 redirect itself, but I don't know if it can do something like that or not.
17 >> For what it's worth, here's the change I made to the module:
21 if ($ENV{REQUEST_URI} !~ /ikiwiki\.cgi/) {
22 my $page = cgi_page_from_404(
23 Encode::decode_utf8($ENV{SERVER_NAME} . $ENV{REQUEST_URI}),
24 $config{url}, $config{usedirs});
25 IkiWiki::Plugin::goto::cgi_goto($cgi, $page);
28 # if (exists $ENV{REDIRECT_STATUS} &&
29 # $ENV{REDIRECT_STATUS} eq '404') {
30 # my $page = cgi_page_from_404(
31 # Encode::decode_utf8($ENV{REDIRECT_URL}),
32 # $config{url}, $config{usedirs});
33 # IkiWiki::Plugin::goto::cgi_goto($cgi, $page);
