Name

http_rewrite — Clears output written to a string output or to an HTTP

Synopsis

http_rewrite ( in stream any );
 

Description

This clears any previous output to the stream. If the stream is omitted or 0 the stream is the HTTP client stream of the calling procedure.

All output from VSP page procedures is buffered into a local string stream before being sent out. This is done so as to support the HTTP/1.1 required content length and to allow recovery from errors.

Parameters

stream

Optional stream to clear. Null or zero (0) implies the default HTTP client stream.
