Subject Re: Android Cordova FileTransfer.upload generates 503 errors with some web servers.
Date Tue, 30 Oct 2012 14:53:20 GMT
I would have loved to have used the Apache HttpClient package but we are
trying to stay away from external dependencies.

When you set chunkedMode to false I know that the transfer worked as per
your comment on JIRA. I will update the docs to mention Nginx servers.
