hecho
=====

hecho is a fast and simple HTTP echo server.

An example is running on "http://hecho.bigode.net/".

It uses Falcon_ HTTP library and Bjoern_ WSGI server to serve thousands
requests per second using just one CPU Core and approximately 15MB of RAM.

The response is a "prettified" json containing the request.

Simple request/response example::

    $ curl --header "Content-Type: application/json" \
        --request POST --data '{"user": "john", "pass": "1234"}' \
        http://localhost:8000?p=param

    {
        "headers": {
            "ACCEPT": "*/*",
            "CONTENT-LENGTH": "32",
            "CONTENT-TYPE": "application/json",
            "HOST": "localhost:8000",
            "USER-AGENT": "curl/7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.27.1 zlib/1.2.3 libidn/1.18 libssh2/1.4.2"
        },
        "json": {
            "pass": "1234",
            "user": "john"
        },
        "method": "POST",
        "origin": "127.0.0.1",
        "params": {
            "p": "param"
        },
        "url": "http://localhost:8000/?p=param"
    }

It supports get, post, put, patch and delete methods.

The request data must be JSON or x-www-form-urlencoded (standard simple post).
