IIS7 has compression turned off and the php.ini has both zlib.output_compression=on and zlib.output_compression_level=-1 set. The page is merely a phpinfo() page. Here the simple ping pong: GET /i.php HTTP/1.1 Host: localhost Connection: keep-alive Cache-Control: max-age=0 User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.79 Safari/535.11 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Encoding: gzip,deflate,sdch Accept-Language: de-DE,de;q=0.8,en-US;q=0.6,en;q=0.4 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 HTTP/1.1 200 OK Content-Type: text/html Content-Encoding: gzip Vary: Accept-Encoding Server: Microsoft-IIS/7.5 X-Powered-By: PHP/5.4.1RC1-dev Date: Mon, 19 Mar 2012 14:00:09 GMT Content-Length: 6182 The output compression seems to work. @info at ongod dot org Could you please try such a simple page scenario and post the request/response headers? ------------------------------------------------------------------------ [2012-03-19 14:01:26] nacin at wordpress dot org I can confirm that WordPress 3.3.1 does not set zlib.output_compression. Looks like WP never has. ------------------------------------------------------------------------ [2012-03-19 11:40:20] info at ongod dot org Security reasons, I would also send an email to you. ------------------------------------------------------------------------ [2012-03-19 11:25:40] mike@php.net zlib.output_compression can be disabled at runtime at later stage in PHP 5.4. I'd probably be lost on a Windows box, so I don't think I could help you there. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
