I first looked at apache and reconfigured it to serve filesize mtime etags. To no avail. When investigating further i discovered that uploaded files get an etag from ms-files.php (line 57) {{{ $etag = '""' . md5( $last_modified ) . '""'; }}} which to my humble opinion should be something like: {{{ $etag = '""' . md5( $last_modified . filesize($file)) . '""'; }}} that way, images of different formats, created at upload time, which share the same mtime on a fast machine still get different etags." defect (bug) closed normal Multisite 3.3.2 normal worksforme has-patch
