When using mod_deflate in Apache2, Apache will chunk gzipped content, setting the Transfer-encoding: chunked header. While this results in a faster download time, I cannot display a progress bar.
If I handle the compression myself in PHP, I can gzip it completely first and set the Content-length header, so that I can display a progress bar to the user.
Is there any way to change Apache's behavior, and have Apache set a Content-length header instead of chunking the response, so that I don't have to handle the compression myself?
