## 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>

Override: | Options
Status: | Base
Module: | mod_reflector
