It would be great if yaws was split into more components like that. We
only use it because it's a working HTTP server protocol
implementation. We're serving appmods from it, and nothing else (not
even static files). We've also got all of the logging shut off because
we have application-specific logs. I would prefer a lighter and easier
to understand solution than Yaws, but I couldn't find an alternative
HTTP implementation that was half-decent and didn't suffer from the
same kind of monolithic bloat that yaws and httpd do.

On another note, when I was prototyping something w/ Yaws yesterday I
thought it would be nice if there was a return value that could be
used to serve a file from disk from an appmod. Right now I just read
the whole thing as a binary and return that, but it would be
preferable if I could just give the path to yaws and let it serve the
file... e.g. {file, ContentType, Path}. Maybe even allow IoDevice in
addition to paths to support already open files?
