hi thanx for the reply
i am really confused it is giving no error
can there be any posibility of acess rights
the link has GUI with a file upload option ans a import button.

From your description, this is a standard user page (since you mention
GUI); I'd be inclined to upload a file via a browser, with "fiddler"
running to see what gets sent - looking in particular at any
additional form variables, cookies, etc. You can probably get as much
by looking at the form, but "fiddler" may be easier, especially since
this is http not https (although fiddler 2 works with SSL in IE)

The top one (I assume this is the one that doesn't work?) has no
Authorization header... this would be my first guess (although you
have set credentials...)

I was mainly looking for cookies and other form variables, but there
don't appear to be any in either ;-(

[Marc Gravell]

Well, from your stack trace it doesn't seem to be using it... I'm
confused as to why you are doubling up on setting headers anyway:
surely .Credentials should manage the Authorization header (so why set
twice?) Likewise, the content-type of a file upload isn't application/
x-www-form-urlencoded, but multipart/form-data. You don't should
netCred being initialized, but I can't see why this isn't playing
ball...

thanx marc
but any how is it possible that the server is not providing the
sufficient rights to upload the data in this way.I was reading in some
article that the portal should me deployed in a anonymous mode. Is it
true.??
