Google PageSpeed says this:Avoid landing page redirectsTo speed up page load times for visitors of your site, remove as many  landing page redirections as possible, and make any required  redirections cacheable if possible.http://xyz.com/ is a cacheable (30 days) redirect to http://www.xyz.com/I'm using PHP and I defined:if ($_SERVER['SERVER_NAME']!=localhost) {define('SITE_URl', http:// www.abc.com/);}.. so please tell me how to do cache-able redirection?
How can I make redirections cacheable to speed up load times?
