Lighttpd

Hello.
I ask to help.
I try to adjust lighttpd and tomcat balancing. Tomcat everything normally works.
I adjust lighttpd. web server rises and opens a page.
I connected the mod_proxy module I adjusted balancing why that won't redirect.
Here mod_proxy.conf config
proxy.balance = "hash"
Lighttpd works for 90 port ##

1. Handle all jsp requests via 192.168.0.101 ##
   proxy.server = ( ".jsp" =>
   ( "tomcat" =>
   (
   "host" => "172.21.21.88",
   "port" => 8080
   ),
   ("host" => "172.21.21.88",
   "port" => 80
   )
   )
   )
