I’m using lighttpd serving mongrel backends. I have the following  
rewrites in my lighty conf file:  
url.rewrite += ( “^/$” =\> “/cache/index.html” )  
url.rewrite += ( “^([^.]+)$” =\> “/cache/$1.html” )

If a page has already been cached (and exists in public/cache), it  
gets served properly. However, if the page hasn’t  
yet been cached, mongrel is looking for the cached page, can’t find it  
and throws a Routing Error.

What do I need to do to correct this?
