4a3b6b890a52931991a7ed042d5973ef2039c623minfrin
4a3b6b890a52931991a7ed042d5973ef2039c623minfrin <p>This module allows request bodies to be reflected back to the
4a3b6b890a52931991a7ed042d5973ef2039c623minfrin client, in the process passing the request through the output filter
4a3b6b890a52931991a7ed042d5973ef2039c623minfrin stack. A suitably configured chain of filters can be used to transform
6d20aeba2c4aa0938bc6e0659d13adc7670ff421poirier the request into a response. This module can be used to turn an output
4a3b6b890a52931991a7ed042d5973ef2039c623minfrin filter into an HTTP service.</p>
