Php – mod_headers not working for php + mod_fastcgi pages

apache-2.2fastcgiPHP

I'm running PHP through mod_fastcgi & mod_suexec, and I added Header set X-UA-Compatible "IE=edge env=best-standards-support" to my .htaccess file. It works fine for static content, but the PHP files lack the header. How do I fix this problem?

Try Header always set X-UA-Compatible "IE=edge env=best-standards-support".

Please note that such a header isn't saved into the files, rather into the HTTP response environment.

If the above doesn't work, try to grab the HTTP response with either curl -I exampmle.org or for example a Firefox Addon called Live HTTP Headers to se if it's set.
