Lighttpd

just do something like this:
var.url = ( "^/$" => "http://localhost", "^/(.*)$" => "http://localhost/$1" )

the goal was to do
'url.redirect = var.url'
later :-7

sadly its not possible to do either this, nor to "regex" on var.*

nevertheless- i guss, lighty should not say:'Segmentation fault (core dumped)'

Full Error Message:
