Hey, I've been thinking about this for a while but can't make a final decision so I want to ask you about your experience and opinions on this matter. I am planning to enable automatic compression to files and expiration times to static files but I wonder which method would be better performance wise. 1. Apache mod_deflate and mod_expire modules using .htaccess configuration? 2. Bytecode PHP using headers (last-modified, etc.) and output buffering and for static files (js, css, images) reading these files and creating an etag and expiration headers?
