Description

When FileTransfer.download() is downloading a file from file:///, NSURLConnection did not return with NSHTTPURLResponse. This will fail for apps that copy files from www/, e.g. apps that initialize its database from a pre-built cache packaged in IPA.

In CB-1600 (fixed in 2.2.0), the fix assumes all response must be NSHTTPURLResponse. So when FileTransfer.download() is downloading from a file:/// URL (e.g. copying file from www/ folder to Documents/), FileTransfer assumed the download operation failed and returned 403.

Tested if we comment out CB-1600, downloading from file:/// works again.

We need to find out a better fix instead of commenting out CB-1600.

According to http://developer.apple.com/library/ios/#documentation/Cocoa/Conceptual/URLLoadingSystem/URLLoadingSystem.html#//apple_ref/doc/uid/10000165i, URL of file:/// is supported.

You can test FileTransfer.download() by calling it with "encodeURI(document.location.href)" as the "source" parameter.
