CoHTTP is an OCaml library for creating HTTP daemons. It has a portable HTTP parser, and implementations using various asynchronous programming libraries:
Cohttp_lwt_unixuses the Lwt library, and specifically the UNIX bindings.
Cohttp_asyncuses the Async library.
Cohttp_lwtexposes an OS-independent Lwt interface, which is used by the the Mirage interface to generate standalone microkernels (see the xen and unix respectively).
You can implement other targets using the parser very easily. Look at the
lib/IO.mli signature and implement that in the desired backend.
You can activate some runtime debugging by setting
COHTTP_DEBUG to any
value, and all requests and responses will be written to stderr.
For build requirements, please see the
_oasis file, or use OPAM to install
it from http://github.com/ocaml/opam.
Simple HTTP server
If you install the Async dependency, then a
cohttp-server binary will also be
built and installed that acts in a similar fashion to the Python
SimpleHTTPServer. Just run
cohttp-server in a directory and it will
open up a local port and serve the files over HTTP.
