I'm trying to build a routine that will take a specified file from the
user's local hard drive, and copy it to a remote server via WebDAV. I've
tried using both HttpWebRequest and FileWebRequest, as outlined in some
samples I found on MSDN and elsewhere, but so far have had no luck
whatsoever. The copy process doesn't fail, but neither does the targeted
file actually appear on the destination server. I have verified that I can
copy files manually to the target WebDAV folder, via a mapped network
resource on Windows XP. Word XP successfully loads and saves files to the
target folder as well.
Here's the code I'm using:
Dim MyResponse As HttpWebResponse
Dim MyCredentialCac he = New System.Net.Cred entialCache
Dim UserName As String = "MyUserName "
Dim Password As String = "MyPassword "
Dim Domain As String = "MyDomain"
Dim SourceURI As String = "http://localhost/text.xml"
Dim MyRequest As HttpWebRequest = CType(WebReques t.Create(Source URI),
HttpWebRequest)
Try
MyCredentialCac he.Add(New System.Uri(Sour ceURI), "NTLM", New
System.Net.Netw orkCredential(U serName, Password, Domain))
' Add the network credentials to the request.
MyRequest.Crede ntials = MyCredentialCac he
MyRequest.Heade rs.Add("Destina tion",
"http://DestinationServ er/SubFolder/text.xml")
MyRequest.Heade rs.Add("Overwri te", "F")
MyRequest.Metho d = "COPY"
MyResponse = CType(MyRequest .GetResponse(), HttpWebResponse )
MyResponse.Clos e()
Catch ex As Exception
MsgBox(ex.Messa ge)
End Try
The status code contained in the response object will say "Created" every
time, but no actual file appears. I have also used a slightly modified
version of this code that uses FileWebRequest instead of HttpWebRequest,
with similar results. Essentially, in that case, the response object
contains a stream that appears to have all the data from the source file in
it, but the file itself never appears in the target folder. Any insight
would be greatly appreciated!
Thanks,

I'm not sure, bu I think you must also stream the data up to the server. But that's just a guess.
If you're not sure what's happening behind the doors then I'd try a packet sniffer and monitor the actual request going out - there
you should see if your file data actually makes it over the wire. Try www.ethereal.com for a nice freeware packet capture.

Markus,
I found the solution, and you are correct. It is the responsibility of the
client to also stream the data to the server. Unfortunately, Microsoft's
own article and sample code fail to mention this small fact, for some
reason.
I actually found an even simpler way to do these types of copy. ADO with
the Internet Publishing provider can handle it, and that's the method I
went with.
Thanks,
Shannon

Has anyone used pure python to upload files to a webdav server over SSL?
I have no control over the server. I can access it with all of the

this:

My goal is to upload files automatically with a python script. The
