note 79880 added to function.header

http://www.sitepoint.com/article/caching-php-performance http://www.sitepoint.com/article/php-anthology-2-5-caching I did find this excellent tutorial which explains in detail how to control client-side cache with headers and implement a server-side cache as well. Its 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. May have another way to get the IF-MODIFIED-SINCE header in CGI mode, but I don't know. ---- Server IP: 200.185.109.13 Probable Submitter: 201.21.74.228 ---- Manual Page -- http://www.php.net/manual/en/function.header.php Edit -- https://master.php.net/note/edit/79880 Del: integrated -- https://master.php.net/note/delete/79880/integrated Del: useless -- https://master.php.net/note/delete/79880/useless Del: bad code -- https://master.php.net/note/delete/79880/bad+code Del: spam -- https://master.php.net/note/delete/79880/spam Del: non-english -- https://master.php.net/note/delete/79880/non-english Del: in docs -- https://master.php.net/note/delete/79880/in+docs Del: other reasons-- https://master.php.net/note/delete/79880 Reject -- https://master.php.net/note/reject/79880 Search -- https://master.php.net/manage/user-notes.php
