HTML5 offline cache doesn't seem to work
hi all,
trying understand how html5 offline cache works, can develop offline web apps, , having real hard time @ it. in fact, i've been testing on , off since last 3 weeks. i've read numerous tutorials, including docs on offline cache available @ developer.apple.com. far haven't gotten work properly.
set cache manifest this:
notice there no resources depend on server, leave network: section blank (the apple dev docs required, though not including makes no difference).code:cache manifest index.html icon.jpg network:
set index.html this:
i have set .htaccess file correct mime-type:code:<!doctype html> <html manifest="cache.manifest"> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8" /> <meta name="viewport" content="user-scalable=no, width=device-width, initial-scale=1.0, maximum-scale=1.0"/> <meta name="apple-mobile-web-app-capable" content="yes" /> <meta name="apple-mobile-web-app-status-bar-style" content="black" /> <link rel="apple-touch-icon" href="icon.jpg"/> <script> cache = window.applicationcache; cache.onchecking = function() { statbar.innerhtml="status: checking"; } cache.ondownloading= function() { statbar.innerhtml="status: downloading"; } cache.oncached = function() { statbar.innerhtml="status: cached:"; } cache.onerror = function() { statbar.innerhtml='status: error ocurred.'; } cache.onupdateready= function() { statbar.innerhtml='updated'; } cache.onprogress= function() { statbar.innerhtml = statbar.innerhtml + "progress!"; } </script> <title>new web project</title> </head> <body> <h1>new web project page</h1> <div id="statbar">status:</div> <script> statbar = document.getelementbyid("statbar"); </script> </body> </html>
when accessed on ipod, progress div displays "checking" "downloading" few times, throws onerror event, displaying "an error ocurred". and, if add home screen , click on it, opens followed "no connection" message, closes automatically.code:addtype text/cache-manifest .manifest
know doesn't have objective-c, still has ios programming, question not banned being off-topic. not asking here if didn't feel i've run out of other online resources me troubleshoot problem. so, if can tell me i'm doing wrong, appreciated. (the pages hosted on http://www.factordice.com/html5).
please, if has information on issue, appreciate help. if ios not support html5 offline caché, i'd know (although information on developer.apple.com claims does). i've run out of options, , still not know doing wrong. in anticipation.
