14.1.9.Chunked Transfer Encoding

Virtuoso supports HTTP 1.1 Chunking Encoding which allows Virtuoso to send the user agent chunks of output as the page is still processing. Chunking is enabled by calling http_flush(1) within the VSP page. Chunks are sent for every 4k worth of output generated. Chunked mode requires the following conditions:

no "Content-Length" header sent to the client using http_header()

no "Content-Encoding" header sent to the client using http_header()

use http_xslt() is not permitted

The client supports HTTP 1.1

Failing these conditions, http_flush(1) will be a No-Operation.

Chunked mode is not supported for static content.
