Content-Encoding and Content-Length headers, just don't send them
in the first place!
* Suppress Content-Length from wfOutputHandler if $wgDisableOutputCompression set
* Fix typo that caused $wgDisableOutputCompression to *enable* instead of *disable* compression ;)
The ob_start() section should preferably be removed from older
LocalSettings.php files.
* Give Content-Length header for HTTP/1.0 clients.
* Partial support for Flash cross-domain-policy filtering. Text entry points should be protected, but uploads are not.
