note 79868 rejected from function.header by betz

Note Submitter: Edemilson Lima - pulstar at gmail dot com ---- http://www.sitepoint.com/article/caching-php-performance http://www.sitepoint.com/article/php-anthology-2-5-caching I did find this excellent tutorial and it explain in detail how to control client-side cache with headers and implement a server-side cache as well. It examples are really useful to bring more performance to your site, but pay attention that getallheaders() and apache_request_headers() only work when PHP is running as an Apache module. Unfortunatelly, these functions are not available when PHP run as a CGI/FastCGI. Do anybody here know another way to get the IF-MODIFIED-SINCE header in CGI mode?
