Re: HTML5 Offline apps with Django 1.4

Thanks for the reply, Russell. I had tried it already. What I get when I do this is, the html source instead of the web page. That is, the complete html code gets printed out in the browser and it happens in all browsers irrespective of mobile, desktop.

Trying to implement offline feature of HTML5.  Deployed in apache2.2 with mod_wsgi plugin.
It works as expected (i.e., loads the cached page when offline) in chrome, Opera (using window.openDatabase) and other desktop browsers. However it doesn't work in Android 2.x, iPhone default browsers. Strangely, it works with Android 4.0 browser!!
Here is the code:

HTML
<!DOCTYPE HTML>      <html manifest="{{MEDIA_URL}}cache.manifest">         <head>            <meta charset="utf-8">                  <title>MyHomeStuff</title>                  <script type="text/javascript" src="{{MEDIA_URL}}MyHomeStuff.js" ></script>            <script></script>         </head>         <body>           .............         </body>      </html>

Apache conf\mime.types  text/cache-manifest manifest

\Python27\Lib\mimetypes.py  Added '.manifest': 'text/cache-manifest', into types_map dict
(With the above addition to mimetypes.py, it started working for android 4.0)

cache.manifest  CACHE MANIFEST
  CACHE:  index.html  MyHomeStuff.js

views.py:
def offlineApp(request):      t = get_template('index.html')      html = t.render(Context({'MEDIA_URL':'http://myDomain.com/site_media/'}))      return HttpResponse(html)

Is it required to use any specific module/middleware to handle text/manifest in django ?
Any help is appreciated. Already spent a lot of time on this!
