Fixes bug
When PHP has zlib.output_compression enabled, it compresses all pages output,
regardless of their HTTP status code. Even empty pages get a ~13 byte empty
gzipped file tacked as their response. Unfortunately, for HTTP status code 304,
this is in direct violation of the specification; furthermore, if SSL and
Keep-Alive are enabled, Firefox gets sufficiently confused such as to post a
download page for the page immediately after the 304 with extra information
afterwards (it mixes up the packets).
I've attached a patch that fixes this bug by manually turning off
zlib.output_compression when a 304 is being sent. I am also coordinating with
PHP's maintainers to get this fixed upstream.
