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?
Is using Free/Open BSD + pf a workable option for filtering DDoS? Which of the two would perform better under heavy load? (SYN flood maxing a 1 gbit pipe)
Is this even an option to consider, or is a full hardware DDoS filter needed to get fast enough performance?
