Background:
I have built a web page that should work even offline. This page is made by following 'AppCache' guidelines.
My web browser is an IE11 on a HP windows 8 tablet.
When I hit the direct URL of the page on the physical server(Oracle weblogic) then I am able to access the page. The same page is accessible via the IE11 browser even when I turn off the network connections.
Issue:
When I access the same page via the corporate gateway(F5 & OHS) then the page is available when there is network connectivity. But once I turnoff the network connectivity then I see the page 'You're not connected to a network'.
When I connect back to the network and try accessing the same page then I can see the resources requested by my page are all served from the local cache browser ( I inspect the network via IE developer tools).
Am not sure what is happening. I would like to access my page even when there is no connectivity.
Note:
My pages are accessible via the gateway using only 'HTTPS'. Where as my direct access to the server is using 'HTTP'
It looks like IE keeps its offline content in different security zones. And these zones vary depending on connected to the network or offline.
It seems when I was connected to the network then the 'Local Intranet' security zone was applied. But when I go offline the 'Internet' security zone was applied by the IE browser.
My web page started working fine when I added the site domain name to the IE -> Internet Options -> Security -> Trusted Sites.
Since then the same security zone was applied when am connected to the network or offline.
