note 82440 added to function.header

hello all ! i'm trying to figure out one thing but can't make it work ... i have index.html and it contains src="x.gif" which browser downloads ... i want to reduce requests to server by setting expire date of that .gif to far future (in case i decide to change .gif i would rename it and adjust src inside index.html) same goes for all external .js and .css ... how can i make all those external files cached permanently on client browser e.g. without browser checking "if-modified -since" on page refresh / reload ? thx in advance ---- Server IP: 69.147.83.197 Probable Submitter: 89.201.141.14 ---- Manual Page -- http://www.php.net/manual/en/function.header.php Edit -- https://master.php.net/note/edit/82440 Del: integrated -- https://master.php.net/note/delete/82440/integrated Del: useless -- https://master.php.net/note/delete/82440/useless Del: bad code -- https://master.php.net/note/delete/82440/bad+code Del: spam -- https://master.php.net/note/delete/82440/spam Del: non-english -- https://master.php.net/note/delete/82440/non-english Del: in docs -- https://master.php.net/note/delete/82440/in+docs Del: other reasons-- https://master.php.net/note/delete/82440 Reject -- https://master.php.net/note/reject/82440 Search -- https://master.php.net/manage/user-notes.php
