Subject: Ensure that output already available is flushed to the network
X-Git-Tag: 2.0.43~6
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e8402764faa501b8d9b4bcd7553d89c58ea34cd8;p=thirdparty%2Fapache%2Fhttpd.git

Ensure that output already available is flushed to the network
when the content-length filter realizes that no new output will
be available for a while.  This helps some streaming CGIs as
well as some other dynamically-generated content.
