What's the rule for character casing in html tags?I have a situation where I need to force no caching on a site of mine. I have been using all lower case for all html tags and attributes (being under the impression that it's case insensitive). I haven't had any issued from this, until now.I have found that the following works on IE7:\[code\]<META HTTP-EQUIV="Expires" CONTENT="-1"><META HTTP-EQUIV="Pragma" CONTENT="no-cache">\[/code\]While this does not:\[code\]<meta http-equiv="Expires" content="-1"><meta http-equiv="Pragma" content="no-cache">\[/code\]FYI I am using PHP and also included the following, but it does not seem to work without the HTML meta tag as well:\[code\]header( "Expires: Mon, 20 Dec 1998 01:00:00 GMT" );header( "Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT" );header( "Cache-Control: no-cache, must-revalidate" );header( "Pragma: no-cache" );header("Content-Type: text/html; charset=UTF-8");\[/code\]EDIT (Added): We have the following doc type (I must admit I am not leet enough to know what this means or how relevant it is)\[code\]<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">\[/code\]
