Jenkins server is not accessible by host name (ip address)
I am trying to use HTML5 Appcache to speed up my web-mobile app by caching images and css/JS files. The app is based on dynamic web pages.

As already known – when using Appcache the calling html page is always cached -> bad for dynamic websites.

My solution - Create a first static page and in this page call the manifest file (manifest="cache.appcache") and load all my cached content.  Then when the user is redirected to another dynamic page the resources will already be available. (Of course this second dynamic page will not have the manifest tag).
The problem is that if the second page is refreshed by the user, the resources are not loaded from the cache; they are loaded directly from the server!

This solution is very similar to using an Iframe on the first dynamic file. I found that the Iframe solution have the exact same problem.

Is there any solution for that? Can Appcache really be used with dynamic content?
Thanks
