Content-Length not sent when gzip compression enabled in Apache?

Content-Length not sent when gzip compression enabled in Apache?

Philippe: "Apache uses chunked encoding only if the compressed file size is larger than the DeflateBufferSize. Increasing this buffer size will therefore prevent the server using chunked encoding also for larger files, causing the Content-Length to be sent even for zipped data."
