An OCaml library for HTTP clients and servers

Cohttp is an OCaml library for creating HTTP daemons. It has a portable HTTP parser, and implementations using various asynchronous programming libraries.

See the cohttp-async, cohttp-lwt, cohttp-lwt-unix, cohttp-lwt-jsoo and cohttp-mirage libraries for concrete implementations for particular targets.

You can implement other targets using the parser very easily. Look at the IO signature in lib/s.mli 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. Further debugging of the connection layer can be obtained by setting CONDUIT_DEBUG to any value.
