FALLBACK cache manifest doesn't work - html

I'm a asp.net developer and I'm using the HTML5 offline features but the FALLBACK isn't working as I expected: when the server is down, instead the page listed of opening the page in FALLBACK is presented the browser standard page of no connection.
In the manifest file I tried:
FALLBACK:
* /Default.htm
and I tried:
FALLBACK:
/ /Default.htm
and the "default.html" page is never opened when the server is down.
I tried in Google Chrome and in Firefox and result is the same.
What I'm doing wrong? Someone can help me?

Carlos Pinheiro

I had a similar issue. Followed every resource online and the only detail that made my manifest work was removing the prefixed '/' before the fallback url.
In your example, change /Default.htm to Default.htm.
FALLBACK:
/ Default.htm

Bypassing HTML5 Offline Appcache

Is it possible to tell your HTML5 Webapp to not load the site from the appcache, if the client has network connection?
This isn't exactly what you're asking, but a way to achieve this is to set up a FALLBACK from / to for example /offline/index.html and then check in the offline index.html if you're online and if you are redirect back to /. That way your normal site is loaded over the internet and your offline version is loaded only when offline.
FALLBACK:
/ /offline/index.html
NETWORK:
*
PS. I have never tried this exact setup, and never even used FALLBACK urls, however I worked a lot with appcaches, so I am pretty sure this should work.

html5 appcahe offline browsing not working fine in chrome?

HTML5 appcache is not working in chrome as expected?
For example
http://html5demos.com/offlineapp
when you load the above URL is will save locally,but when you refresh the page again it will not render properly.
MANIFEST file:
http://html5demos.com/html5demo.appcache
will cache the following files :-
images/shade.jpg
images/bin.jpg
/js/h5utils-offline.js
/css/html5demos.css
expect these files every other resources are not rendering when we refresh the page.
expected behavior:
All other resources(which are not in MANIFEST file) should load properly when user comes online.
but in Firefox this is working almost fine.
Why chrome is not working as expected ?
It will be great if there is some perfectly working demo.
html5 appcache is at risk and may be removed:
http://www.w3.org/TR/html5/
http://w3-video.com/Web_Technologies/HTML5/html5_attributes/html/html5_html_manifest_attribute.php
Non-cached resources will not load on a cached page. See Gotcha #5 from this article:

Using the network wildcard:
NETWORK:
*
...would fix this.

HTML5 Cache Manifest Fallback Page

I am trying to get the Cache Manifest to fallback to an offline.aspx page when offline.
So when the current page that contains the following cache manifest is loaded online it displays as normal, but when there is no internet connection offline.aspx is shown instead of the current page.
CACHE MANIFEST
# v1.39
NETWORK:
*
FALLBACK:
/ /offline.aspx
Is this possible? Am I understanding that you can replace the current page offline with a fallback page? Is my manifest file correct?
I replaced the /s with /*s and it still didn't work. Chrome Developer Tools shows the offline.aspx as in the cache as type 'Fallback' and the default.aspx as 'Master'. When offline the offline.aspx never gets shown - it still shows default.aspx. I'm going offline by disabling the Local Area Connection in the Network Adapters in Windows 7.
Check these examples:
static.html will be served if main.html is inaccessible
offline.jpg will be served in place of all images in images/large/
offline.html will be served in place of all other .html files (for your case try /* or *)
FALLBACK:
/main.html /static.html
images/large/ images/offline.jpg
*.html /offline.html
p.s.:
Your
NETWORK:
*
should be like:
NETWORK:
/ or /*

HTML5 appcache with Chrome and the HTTPS Everywhere plugin causing cross site css not to load

I have run into an issue with one of my webpages that was changed to use the HTML5 appcache feature. Chrome 19 (ad I assume earlier versions) is blocking my cross site css files when the appcache is enabled on a page. The page, http://www.ericperrets.info/index.html, loads a number of image/css files from my server and a number of css files from a google url/servers. Below is the epi.appcache file content
CACHE MANIFEST
#
CACHE:
/default.css
/800px.css
/images/bg.jpg
/images/spwright.png
/images/spwright2.png
/images/meme.jpg
/favicon.ico
/Resume%20-%20Eric%20Perret.pdf
NETWORK:
/index.html
*
http://*
https://*
This works find when the page is loaded in the latest safari or firefox, but when I try to load it in Chrome, it blocks the calls to http://fonts.googleapis.com/css?family=Reenie+Beanie|Candal&v1&text=ERIC%20PT%E2%80%99SINFOAesumWorkaplntcfLidh%2C
Update: I fixed the issue by disabling one of my plug-ins that I had for Chrome: HTTPS Everywhere. This is a really useful plugin. Is there a way around this issue other than changing the URL to https?

HTML5 Manifest only see fallback

Hey guys my Manifest is as follows:
CACHE MANIFEST
CACHE:
images/trunk/text/text-images.png
css/site.css
FALLBACK:
/ offline.html
NETWORK:
*
I've since fixed a random random problem whereby safari couldn't load google maps without NETWORK *. What I now want to do is ensure that if someone is offline they only ever hit that offline.html page, I've noticed its possible to sometimes hit a regular page, which looks relaly broken and then you only get transferred to the fallback page after requesting another page. Is tehre anything I need to add here?
