I have in environment.rb:  
config.action\_controller.page\_cache\_directory = RAILS\_ROOT + “/public/  
cache”

The following rules in lighttpd.conf:  
url.rewrite += ( “^/$” =\> “/cache/index.html” )  
url.rewrite += ( “^([^.]+)$” =\> “/cache/$1.html” )

What I’m seeing is that 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.

I followed this article pretty closely:  
[http://www.railsenvy.com/2007/2/28/rails-caching-tutorial](http://www.railsenvy.com/2007/2/28/rails-caching-tutorial)

Any ideas?
