# Bug Report
## Problem
WkWebView cannot open any pages from data container. There are no issues
with pages in bundle. Application can download and save new pages/resources
into cache folder (cordova.file.cacheDirectory), but attempts to set
windows.location to some page in cache folder fail.
### What is expected to happen?
It worked fine with UIWebView, and it would be great to have the same
possibility with WkWebView
### What does actually happen?
If we load file directly:
`<content src="Bootloader.html" />`
then document location is set to:
`'file:///private/var/containers/Bundle/Application/GUID/InMotionTestApp.app/www/Bootloader.html'`.
We check if cached version exists and try to set location:
`window.location='file:///var/mobile/Containers/Data/Application/GUID/Library/Caches/1.11.00000.0000/www/Default.html'`
Such attempts fail with 'outside sandbox' error, while we try to open files
from sandbox:
```
2021-07-30 10:06:33.742306-0400 InMotionTestApp[2318:560700] [Loading]
Received an unexpected URL from the web process
2021-07-30 10:06:33.742441-0400 InMotionTestApp[2318:560700] [Process]
0x10202ca18 - [pageProxyID=11, webPageID=12, PID=2321] WebPageProxy::Ignoring
request to load this main resource because it is outside the sandbox
```
If we add schema and hostname to config.xml like it's recommended in blog:
```
<content src="app://localhost/Bootloader.html" />
...
<preference name="scheme" value="app" />
<preference name="hostname" value="localhost" />
```
We do not get error in Xcode, but get error in web inspector:
`Not allowed to load local resource:
file:///var/mobile/Containers/Data/Application/A3E5D945-5503-4D23-A54F-C1135CE08CD8/Library/Caches/1.11.00000.0000/www/Default.html
`
Replacing 'file://' with 'app://localhost' does not help, it just generates
404 error.
