Subject: Re: Using Derrick Pallas' ruby fcgi dispatcher

No clue, but I suggest you to add some:

> $stderr.puts "TEST X: #{cgi.params.inspect}"

...all over that dispatcher script to see where the problem starts (it will 
log to lighttpd's error log).

 I also had many problems with fcgi and lighttpd mainly because it was setting 
different environment variables than other webserver (webrick). To fix this I 
first modify the environment table before I continue and so far I have no 
problems:

> class CGI
>   class << self
>     def fix_env(ec)
>       if (ec['PATH_INFO'].nil? || ec['PATH_INFO'] == '') then
>          pi =  ec['REQUEST_URI']
>          pi = pi[0..(pi.index('?')-1)] if pi.include?('?')
>          ec['PATH_INFO'] = pi
>       end
>
>       if (ec['QUERY_STRING'].nil? || ec['QUERY_STRING'] == '') then
>          ec['QUERY_STRING'] = ec['REQUEST_URI'].include?('?') ?
>              ec['REQUEST_URI'].scan(/.?\?(.*)/)[0][0] :
>              ""
>       end
>       ec
>     end
>   end
> end


... and in the dispatcher you do:

> FCGI.each_cgi do |cgi|
>   CGI::fix_env(cgi.env_table)


Maybe that helps...
