In other words, we must NOT store a cache of already-compressed data. This often occurs when a theme attempts to use `ob_start("ob_gzhandler")` in `/header.php`.
That should NOT be done in `/header.php`. If you must use `ob_start("ob_gzhandler")`, place it in: `/wp-config.php` so it's the top-level output buffer.
*Note* If `zlib.output_compression` is enabled, we should EXPECT to see `zlib_get_coding_type()`. It's fine to use `zlib.output_compression`.
