 * Hello dear
 * I like me know it this plugin is compatible with caching plugins (I am using 
   Cachify plugin)
 * Another question, Google not recommended use iframes, do you think this plugin
   is bad for SEO?
 * How can I test the plugin is really working?

 * The plugin is indeed compatible. I’ve added specific support for CDN rewriting
   for W3 Total Cache and plan to add support for others as well.
 * The reason for using an iframe is to prevent your HTML pages being cached offline.
   Once they’re in appcache it’s very difficult to remove or update them so you 
   don’t want that.
 * The iframe contains no actual content, just the manifest reference on the HTML
   tag. I can’t see how it could possibly have a negative effect on SEO. In fact
   page speed is taken into account for SEO now so it should help if anything.
 * To test that the plugin is working you can view the developer console in Chrome
   for example by hitting f12, then under the network panel you can see which assets
   are delivered ‘from cache’. You can also browse to chrome://appcache-internals
   to see what content sites are storing in appcache.
 * Lastly compare the speed of a few page loads using appcache and then again without.
   The biggest advantage is that it speeds your site up for returning users on slow
   connections in particular.

 * Thanks for your explanations.
 * Do you think I no will have problems with my Google Adsense ads?
 * Are you using the plugin on a personal website or similar?
 * I active todady and it shows an interesting improvement in the speed, I worry
   because can cause me some problems because I do not know how far the plugin has
   been tested
 * thank you

 * Hi, the plugin is currently in production on 2 sites:
 * [http://screeningfilm.com](http://screeningfilm.com)
    [http://babb.telegraph.co.uk](http://babb.telegraph.co.uk)
 * The plugin only caches static assets from your plugins and theme so the HTML 
   which is typically where the adsense scripts are included shouldn’t be cached.
 * If the main adsense script is added using wp_enqueue_script() it will be added
   to the appcache but there is a filter you can use to exclude it or to force refresh
   the appcache for your users. I’ll add some documentation about that and maybe
   a settings field to make it easy.
