Setting the expiration data on files will "order" the browser to save those in cache for X amount of days. you can set this header on File/Folder

Thank you for quick response. Is the only way to do it? can I specify expiration for each file separately? for example for some of the files I need to set expiration after 7 days and for other files after 1 month

yes you can, you can do it on a folder and/or on a file, with no problem at all.
