# Apache Module mod_reflector

Description: | Reflect a request body as a response via the output filter stack.
Status: | Base

## Examples

Compression service
  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.

      <Location "/compress">
          SetHandler reflector
          SetOutputFilter DEFLATE
      </Location>

Image downsampling service
  Pass the request body through an image downsampling filter, and reflect the results to the caller.

      <Location "/downsample">
          SetHandler reflector
          SetOutputFilter DOWNSAMPLE
      </Location>

## ReflectorHeader Directive

Description: | Reflect an input header to the output headers
Syntax: | `ReflectorHeader inputheader [outputheader]`
Context: | server config, virtual host, directory, .htaccess
Override: | Options
Status: | Base
Module: | mod_reflector

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.
