Lighttpd and cgi python
===

I'm trying to execute some python scripts through lighttpd but when I try to run it, I only get a blank file which I'm asked to download.

_lighttpd.conf_

    server.modules	= (
                "mod_access",
                "mod_alias",
                "mod_accesslog",
                "mod_compress",
    			"mod_rewrite"
    )
    
    server.port 		    	= 8080
    server.bind 		    	= "127.0.0.1"
    server.document-root        = "/var/www"
    server.upload-dirs          = ( "/var/cache/lighttpd/uploads" )
    server.errorlog             = "/var/log/lighttpd/error.log"
    server.pid-file             = "/var/run/lighttpd.pid"
    server.username             = "www-data"
    server.groupname            = "www-data"
    
    
    
    index-file.names            = ( "index.php", "index.html",
                                    "index.htm", "default.htm",
                                   " index.lighttpd.html" )
    
    
    url.access-deny             = ( "~", ".inc" )
    
    static-file.exclude-extensions = ( ".php", ".pl", ".fcgi", ".py" )
    
    dir-listing.encoding        = "utf-8"
    server.dir-listing          = "enable"
    
    compress.cache-dir          = "/var/cache/lighttpd/compress/"
    compress.filetype           = ( "application/x-javascript", "text/css", "text/html", "text/plain" )
    
    include_shell "/usr/share/lighttpd/create-mime.assign.pl"
    include_shell "/usr/share/lighttpd/include-conf-enabled.pl"

_/etc/lighttpd/conf-enabled/10.cgi.conf_

    server.modules += ( "mod_cgi" )
    
    $HTTP["url"] =~ "^/cgi-bin/" {
    	cgi.assign = ( "" => "" )
    }
    
    ## Warning this represents a security risk, as it allow to execute any file
    ## with a .pl/.py even outside of /usr/lib/cgi-bin.
    #
    cgi.assign      = (
    #	".pl"  => "/usr/bin/perl",
    	".py"  => "/usr/bin/python"
    )

_/var/www/cgi-bin/hellopy.py_

    print "Content-Type: text/html"
    print
    print "<TITLE>CGI script output</TITLE>"
    print "<H1>This is my first CGI script</H1>"
    print "Hello, world!"

I really don't understand what's happening =/

Thanks
