AJAX获取页面不在清单上

With a cached HTML page and JQuery, It seems it is impossible to get a page from the server that was not listed on the manifest. Any time I try to access a page not on the manifest, it always returns null, or "". Has anyone managed to access a page not on the manifest? If so, how? This code will deployed on Webkit(nightly build).

Got It! Pretty simple too... I forgot to add the following to cache

CACHE MANIFEST
NETWORK:
*
CACHE:
index.php
...

The NETWORK: allows ajax to get any pages not on the cache
