4142	Etags for profile icondirect.php and groups icon.php	codelust	sembrestels	"icondirect.php does not output Etags. It only carries an expires header, which is good, but may not be enough. On the production site that I run, the ETags header has made a considerable improvement in page load times. You may want to explore adding ETags to icondirect.php.

Code I have changed:


header(""Content-type: image/jpeg"");
                                header('Expires: ' . date('r',time() + 864000));
                                header(""Pragma: public"");
                                header(""Cache-Control: public"");
                                header(""Content-Length: "" . strlen($contents));
                                $eTag = ""elgg-"".dechex(crc32($contents));
                                header(""ETag:$eTag"");
                                $splitString = str_split($contents, 1024);
                                foreach($splitString as $chunk) {
                                echo $chunk;
