我运行一个DHTML页面，想要缓存被引用的HTML，PHP文件和图像文件。
I am running a DHTML page and want to cache the HTML, PHP file and IMAGE files that are referenced.
我在WWW.sitename.COM/sub-dir /
I have all the following files in WWW.sitename.COM/sub-dir/
的.htaccess
.htaccess
AddType application/x-httpd-php .html
AddType application/x-httpd-php .htm
AddType text/cache-manifest .manifest
AddHandler server-parsed .html
AddHandler application/x-httpd-php .html .htm
cache.manifest
cache.manifest

http://WWW.sitename.COM/sub-dir/this.php
http://WWW.sitename.COM/sub-dir/images/first.png

FALLBACK:
HTML中THIS.PHP文件清单参考...
HTML manifest reference in THIS.PHP file...
<html manifest="http://WWW.sitename.COM/sub-dir/cache.manifest">
脚本检测缓存活动
script to detect cache activity
<script type="text/javascript">
var cacheStatusValues = [];
cacheStatusValues[0] = 'uncached';
cacheStatusValues[1] = 'idle';
cacheStatusValues[2] = 'checking';
cacheStatusValues[3] = 'downloading';
cacheStatusValues[4] = 'updateready';
cacheStatusValues[5] = 'obsolete';
var cache = window.applicationCache;
cache.addEventListener('cached', logEvent, false);
cache.addEventListener('checking', logEvent, false);
cache.addEventListener('downloading', logEvent, false);
cache.addEventListener('error', logEvent, false);
cache.addEventListener('noupdate', logEvent, false);
cache.addEventListener('obsolete', logEvent, false);
cache.addEventListener('progress', logEvent, false);
cache.addEventListener('updateready', logEvent, false);
function logEvent(e)
{
var online, status, type, message;
online = (navigator.onLine) ? 'yes' : 'no';
status = cacheStatusValues[cache.status];
type = e.type;
message = 'online: ' + online;
message+= ', event: ' + type;
message+= ', status: ' + status;
if (type == 'error' && navigator.onLine)
{
message+= ' (probably a syntax error in cache.manifest)';
}
console.log(message);
}
window.applicationCache.addEventListener(
'updateready',
function(){
window.applicationCache.swapCache();
console.log('swap cache has been called');
},
false
);
setInterval(function(){cache.update()}, 10000);
</script>
控制台报告说，没有什么是被缓存。
The console reports that nothing is being cached.
