<description>Reflect a request body as a response via the output filter stack.</description>

<identifier>reflector_module</identifier>

<summary>
    <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>
</summary>

<section id="examples"><title>Examples</title>
    <dl>
    <dt>Compression service</dt>
    <dd>Pass the request body through the DEFLATE filter to compress the
    body. This request requires a Content-Encoding request header containing
    "gzip" for the filter to return compressed data.
    <highlight language="config">
&lt;Location "/compress"&gt;
    SetHandler reflector
    SetOutputFilter DEFLATE
&lt;/Location&gt;
    </highlight>
    </dd>

    <dt>Image downsampling service</dt>
    <dd>Pass the request body through an image downsampling filter, and reflect
    the results to the caller.
    <highlight language="config">
&lt;Location "/downsample"&gt;
    SetHandler reflector
    SetOutputFilter DOWNSAMPLE
&lt;/Location&gt;

<usage>
    <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>
