Subject: [BUG] http_server_error() must not purge a previous pending response
X-Git-Tag: v1.4-dev7~5

[BUG] http_server_error() must not purge a previous pending response

This can cause parts of responses to be truncated in case of
pipelined requests if the second request generates an error
before the first request is completely flushed.
