Nginx gzip and Vary. How to
I want to output "Vary: Accept-Encoding,User-Agent".
But gzip_vary only adds Accept-Encoding. "add_header Vary" does not merge headers.
My answer is..
location / { gzip on; gzip_disable "MSIE [1-6]\."; gzip_types text/css application/x-javascript; gzip_vary off; if ( $request_filename ~ "\.(html|css|js)$" ) { add_header Vary "Accept-Encoding,User-Agent"; } root /path/to/htdocs }
MSIE < 7 have a bug around gzip and cache. Do not response compressed javascript/css for those browser.
