html - CSS cache update and CDNs -
when develop web applications, i'm used add ?ver=xxx @ end of css uris.
i'm updating wordpress theme , found filter removes ?ver= "static ressources" :
add_filter( 'script_loader_src', 'mb_remove_script_version', 15, 1 ); add_filter( 'style_loader_src', 'mb_remove_script_version', 15, 1 );
searching web found without removing thoses ver=, cdn may not work , not cache css files ! that's big surprise me used everywhere.
i use version force browsers update cache when modify css (by versionning up). how force browser understand file must downloaded again without using ver= ?
