Cache manifest chrome reload behavior - html

I'm using a dynamic cache manifest and when I reload the browser after the initial load, the browser doesn't pull certain assets.
Here's the generated cache:

After the cache checking event it fails to load these resources when I reload the browser:
I disabled google fonts so it wouldn't fail on that but it still failed on the others.


Provide the below lines (Network Section) after cache section
NETWORK:
NETWORK:
*
http://*
https://*


So, I figured out why it's not working. Some of the libraries don't have cache expiration values. So, notice all the files that fail have ?ver=##. I removed all the version numbers that are referenced and it worked!

Is there limit to number of files that can be cached in html5 manifest?

I have lot of .PNG images numbering from 1 to 259 with a total size 250kb. I need these images to be available as thumbnails when the app is used in offline mode. So I created the manifest including all of these resources and then added the manifest to the homepage of the app using the html5 directive but the app failed to run offline.
Here is the manifest below;

I have used manifest before but with limited number of files which works fine... I don't know why this is failing to work. Is there a way out of this? Any workable solution will be well appreciated.
Thank you.

What is the nested tables limit for major browsers?

Backstory: When working with Microsoft Dynamics CRM, I discovered a document from Microsoft stating that every browser has a specific limit of how many nested tables you can have.
There is a limit to the number of nested steps you can use in a dialog. The limit depends on the browser you’re using and isn’t a limit in Microsoft Dynamics CRM. The nested steps are rendered in the browser as nested tables. Some browsers support more levels of nested tables than others.
Source
I have read this question but it is more generalised into ANY element, rather than a table in a table, which is what I am seeing.
What are the real-world limitations for major browsers?
From my real-life example, I am looking at approximately 61 nested tables. Although, I am unsure, as copying the entire page source reveals 6 opening <table> tags and 61 </table> tags

As noted by #Alex, Firefox is currently limited to 33 nested tables. Cross-browser, this represents the current practical nested table limit. Your 61 nested tables will not currently render in Firefox.
Let's go further and make a real-life test. We can open a new nested table on each line and let the browser fill in the closing tags:
<table><tr><td>1
<table><tr><td>2
<table><tr><td>3
<table><tr><td>4
<table><tr><td>5
<!-- ad infinitum -->
Results
I tested Internet Explorer 11, Firefox (Windows + Android) and Chrome (Windows + Android) — Edge and Safari would be useful to test as well.
Most nested tables rendered
Internet Explorer 11 managed to render 262 nested tables correctly. Any more would be rendered briefly before crashing the browser.
Runner up
Google Chrome (Version 53.0.2785.143 m (64-bit)) manages to render 378 nested tables, but only the first 127 are rendered correctly, with the rest breaking out of the outermost table. Any further nested tables caused the tab to crash. This behaviour is the same on mobile.
Least
Firefox (Version 49.01) only managed to render 33 nested tables correctly. The following nested tables were simply not rendered and the browser did not crash even when 1000 nested tables were given to it. This behaviour is the same on mobile.
Try it yourself
Here are 1000 nested tables. Note: Testing all 1000 tables will probably cause your browser to crash.

border: 1px solid #000;

IE11 crashs on html5-audio in Citrix XenApp7.6 on Ipad Air with iOS 8.1.3

I'm investigating a curious problem with crashing IE11.
Our Environment is a website running in IE11 deployed via Citrix Xenapp to iPads with Citrix Receiver.
IE11 11.0.9600.17631
XenApp 7.6
Windows 2012 R2
Citrix Receiver 5.9.4
iOS 8.1.3
In approx. 10% the cases of opening the website the crash of IE occurs.
The use case is, that we want to play a sound when buttons are pushed.
Investigation
We nailed it down to the html5 audio tag which causes the trouble.
So we built two minimal examples for reproducing this failure behaviour.
On with plain html5 audio tags and the other with scripted audio elements:
<!-- audio1.html -->
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
</head>
<body>
<audio id="player" controls preload="auto">
<source src="img/sound/beep.mp3" type="audio/mpeg" />
<source src="img/sound/beep.ogg" type="audio/ogg" />
<source src="img/sound/beep.wav" type="audio/wav" />
</audio>
<audio id="player2" controls preload="auto">
<source src="img/sound/beep2.mp3" type="audio/mpeg" />
</audio>
<audio id="player3" controls preload="auto">
<source src="img/sound/beep3.mp3" type="audio/mpeg" />
</audio>
<audio id="player4" controls preload="auto">
<source src="img/sound/beep4.mp3" type="audio/mpeg" />
</audio>
</body>
</html>
<!-- audio2.html -->
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
</head>
<body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
jQuery(document).ready(function() {
function createAudio(url) {
var audio = document.createElement("audio");
audio.setAttribute('preload', 'auto');
audio.setAttribute('controls', 'controls');
audio.setAttribute('type', 'audio/mpeg');
if (audio != null && audio.canPlayType && audio.canPlayType("audio/mpeg")) {
audio.src = url;
}
document.body.appendChild(audio);
return audio;
}
var audio1 = createAudio("img/sound/beep.mp3");
var audio2 = createAudio("img/sound/beep2.mp3");
var audio3 = createAudio("img/sound/beep3.mp3");
var audio4 = createAudio("img/sound/beep4.mp3");
});
</script>
</body>
</html>
Result
With this examples we could reproduce the failure more often
In 20% the website is working normal.
In 10% the audio-players show Ungültige Quelle or Invalid Source.
In 70% the IE crashs.

As I understand the crash dump IE crashs by registering an audio device. propably for citrix.?
Other attemps for solving this issue
The mp3-files are on the same server
The problem occurs wether the site is deployed via PHP and Apache or NodeJS
Latest Firefox and Chrome (40.0.2214.93) are showing the sites correctly.
Opening the site via Console as Admin IE11 doesn't crashs but shows Invalid Source in most times
Citrix HdxMediaStreamForFlash registry-keys were set.
Server does not compress the mp3s and sends them with MIME audio/mpeg.
Other already regarded Questions from SO with no suitable solution for our problem
How do I get a HTML5 Video to work using IE10
IE10 not playing a video when using the <video> tag, but plays it when requesting the video directly
HTML5 audio element do not work in IE10, but works in Chrome. Why?
"Error: Unsupported audio type or invalid file path" for HTML5 Audio tag in Internet Explorer 10
IE10 Windows7 -- Audio tag never plays audio?
Finally
My problem is now, that i have no idea, what to do to solve this problem.
Is it windows problem, a citrix problem, an iOS problem? Or is it a combination of all
of them.
Does anybody knows a workaround for it?
Or is there another point from which i can start another debugging attempt?
If you need more data, please let me know.
Update 2015-03-10
It is not a problem with iOS or Citrix Receiver, because the crash crash also appeard on a Samsung Galaxy Tab.
The crash occurs for the first time about three and a half hours after a server reboot

Is the XenApp server configured to enable Windows media redirection, ref: http://support.citrix.com/proddocs/topic/xenapp65-admin/ps-sf-media-speed-screen-acceleration-config-all-v2.html. If so, does disabling it fix the issue? The current documentation for Citrix Receiver for IOS has information about settings on this page for media redirection too, ref: http://support.citrix.com/proddocs/topic/receiver-ios-59/receivers-ios-about.html Recommends free space.

For completeness, this were my workarounds:
Reduced the use of audio to a minimum
Rebooting the windows servers every night (Enough for 20 sessions per server per day with 8 hours of active use each)
Our final fix was upgrading to Windows Server 2016 and Citrix Xenapp 7.15 and there, this problem does not occur.
The tickets we opened at microsoft and citrix were closed/rejected with "No problem with our software, it must be the other vendors."

SVG rendering error after update

Im collecting digital signatures, SVG path, with an iPad.
Signatures are viewed with a browser (Chrome) which have worked perfectly for years.
Suddenly it was not perfect, whitespace are added below and to the right of the signature and it messes up my tables. I traced this back to an update of Chrome. If I downgrade Chrome it works like a charm.
Confusing is that same rendering error appears in IE and Firefox! New standard? Anyone knows how to fix this?

Assuming this svg is part of a larger html page then you almost certainly need height and width attributes on the <svg> element. Try height="100%" width="100%"
Firefox has worked this way for years as it's what the specification says. Chrome has recently changed to be compatible with Firefox and the SVG specification.

How to get kml file (Google Maps) using the link?

How to get Google maps kml file using link?
I tried
http://maps.google.com/maps?f=d&hl=en&saddr=-8.703893,115.223558&daddr=-8.36429800000000,115.461588000000&ie=UTF8&0&om=0&output=kml
but it returns Google maps view.
A month ago, I tried that step and got kml:

But now it can't.

Looks like Google no longer supports this url-parameter.
As a workaround you could use other mapping tools like mapfab.com
After saving your map you can download it as kmz-file. (It also offers snapping polylines)

You can get KML attachment instead of map window if you click the google-map route link at https://code.google.com site. So you only need to make a test project there.
