Cgi scripts don't know hostname

ruby-talk

Forgive me if this is a dumb question, but it's got me stumped.

I'm running a WEBrick server and I've mounted HTTPServlet::FileHandler
as follows:

s.mount("/cgi-bin",HTTPServlet::FileHandler,
cgi_dir,{:FancyIndexing=>true})

However, the scripts in the cgi-bin directory can't find the hostname
when they're run by the web server. E.g., the following script

#!/usr/bin/ruby -w

s = %{
        <html>
                <body>
                        Hi #{ENV['HOSTNAME']} Bye
                </body>
        </html>
}
print s

prints the html with the machine name embedded in it when I run it from
the command line, but only "Hi Bye" when I look at it in the browser.
What's up with that?

It turns out that the cgi scripts run this way have an empty or at least
incomplete ENV. I worked around it by marshaling the server's ENV and
having
the cgi's read it at startup. Not a great solution, but it works.
