What steps will reproduce the problem? 1. Created a WebDav share using apache2 2. Entered the URL in the text field of iPhone app 3. Hit either upload / download

What is the expected output? What do you see instead? Should download/upload the document and loading screen with connection status should be removed.

The loading screen remains with Establishing Connection status forever.

Please provide any additional information below.

It looks like depth is not set in the http request header for the server. And by default server assumes a depth of infinity. If server is not configured to accept request with infinity depth it rejects the request with 403 forbidden. Check this link http://tools.ietf.org/html/rfc4918#section-9.1.1

Adding DavDepthInfinity On in apache conf resolved this issue but this is security issue on server side also if server may be some public server so we may not be able to modify server side settings. So setting the request header in init function of WTHTTPConnection resolves this issue. See this link http://tools.ietf.org/html/rfc4918#section-8.3.1

CFHTTPMessageSetHeaderFieldValue(request, @"Depth", @"0")

This should fix the issue.
