Hi All,

if we read performance rules given by yahoo they suggest to add expire header for JS and css files.

my question is how to add expire header for different JS and CSS files.

reference URL :- http://developer.yahoo.com/performance/rules.html#expires

Assume I have a php page that have 5 js and 2 css it may be anywhere in html document for eg

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252" />
<script language="javascript" type="text/javascript" src="test.js"> </script>
<title>Untitled Document</title>
</head>

<body>
<script language="javascript" type="text/javascript" src="test2.js"> </script>
SOME HTNl CONTENT
<script language="javascript" type="text/javascript" src="test3.js"> </script>
<script language="javascript" type="text/javascript" src="test4.js"> </script>
<img src="1.gif">
</body>
</html>

 

My question is how I will add expire header in every JS, CSS and images.

I have a restriction:-  I cannot use ob_start() for the output buffering.
