Lighttpd

Hello.

We are developing heavy-loaded web-service based on lighttpd/xcache/spawn-fcgi. And we came across one problem with our (404-error based) file-caching mechanism. The problem is that mod_ssi instruction does not generate 404 on file not found. As a result 404-error handler is not called and page is not generated.

Is it possible to implement such behaviour in mod_ssi?
