Hi Mike,

Very interesting idea for servers returning plain files...  
However, I was wondering about how you handle:

- Logging requests (for statistical purposes)
- Access control (files that should NOT be serviced)
- Changes in directory indices (is it a smart cache as to notice changes?)
- CGI Scripts (In particular, POST requests and imagemaps)
- Server-Side Includes.

I think that the guys at Yahoo were doing something along these lines,
with a "front-end" HTTP server for basic requests and a "back-end" server
for more complicated ones.

Probably a compiling directive BASIC_HTTPD should be considered
for people with servers that do NOT require any of the mentioned
server capabilities, or just can NOT afford the performance implications. 

- Carlos.
