<h3>Summary</h3>

    <p>This module allows request bodies to be reflected back to the
    client, in the process passing the request through the output filter
    stack. A suitably configured chain of filters can be used to transform
    the request into a response. This module can be used to turn an output
    filter into an HTTP service.</p>

    <p>This directive controls the reflection of request headers to the response.
    The first argument is the name of the request header to copy. If the optional
    second argument is specified, it will be used as the name of the response
    header, otherwise the original request header name will be used.</p>
