Looks like you are setting a 60 minute expires on the static resources: http://www.webpagetest.org/result/140609...ic_content

Find where you are setting the expires in htaccess/httpd.conf and extend it as far as you feel comfortable. Some of the files are versioned and can be extended indefinitely (year). You should consider versioning all of the assets so you don't have to worry about changes getting picked up when you change the files on the server.

got your meaning, then we'll set the apache server conf again for this.

Thank you very much for your reply!!
