a78048ccbdb6256da15e6b0e7e95355e480c2301nd
a78048ccbdb6256da15e6b0e7e95355e480c2301nd <p>This module allows request bodies to be reflected back to the
a78048ccbdb6256da15e6b0e7e95355e480c2301nd client, in the process passing the request through the output filter
a78048ccbdb6256da15e6b0e7e95355e480c2301nd stack. A suitably configured chain of filters can be used to transform
a78048ccbdb6256da15e6b0e7e95355e480c2301nd the request into a response. This module can be used to turn an output
a78048ccbdb6256da15e6b0e7e95355e480c2301nd filter into an HTTP service.</p>
