Details

The purpose of this method is to provide partial writing of HTTP response such that, for instance, a web browser can display parts of an HTML page while the rest is generated. Note that this is only supported by the HTTP v1.1 protocol.

Note: The minimalistic HTTP daemon (written in Tcl) used internally currently only supports HTTP v1.0. In other words, although this class is used already, the output is only flushed at the end.
