Libevhtp was created as a replacement API for Libevent's current HTTP API.
The reality of libevent's http interface is that it was created as a JIT
server, meaning the developer never thought of it being used for creating
a full-fledged HTTP service. Infact I am under the impression that the
libevent http API was designed almost as an example of what you can do with
libevent. It's not Apache in a box, but more and more developers are
attempting to use it as so.
