Thanks Peter for providing https://github.com/yeslogic/httpsrv.
Testing on MacOS was successful.

Installing the dependencies with the Homebrew package manager was as easy as
    $ brew install libuv http-parser

There was an issue with librt, which seems neither to exist nor to be required on Mac. Changing the file https://github.com/yeslogic/httpsrv/blob/master/sample/Mercury.options fixed this:

    - MLLIBS-httpsrv_test += -luv -lhttp_parser -lrt
    + MLLIBS-httpsrv_test += -luv -lhttp_parser

Is it possible to automatically skip '-lrt‘ in the Mercury.options file depending on the compilation target? I'm planning to cross-compile from a MacOS host to a Windows target.
