As the author of H2O, I would like to leave a comment here. First of all, the development is still in early stages, please forgive me for the lack of documentation. That said, below are some high-level design issues that are not addressed by the README. - it is designed to be pluggable (though not as flexible as Apache), by providing virtual-host-based configuration of generators, output filters and loggers - lib/file.c and lib/chunked.c would be a good place to understand their interface if you are interested - I am (at the moment) not interested in providing support for input filters - performance of HTTP parser is likely going to become importance since the ratio of small files being served is expected to increase in HTTP/2; H2O is designed with that in mind
