I have a web site hosted on IIS with windows authentication. I am trying to access it in one of my iPhone web application. Presently i am using this code, but it is not working.

NSString \*authString = [[[NSString stringWithFormat:@"%@:%@", @"myusername", @"mypassword"]dataUsingEncoding:NSUTF8StringEncoding] base64Encoding];

```
authString = [NSString stringWithFormat: @"Basic %@", authString];

**[requestObj setValue:authString forHTTPHeaderField:@"Authorization"];**

```

my web app is hosted with windows authentication. but here i am using basic. can any one post what is the correct http header for it.

Thanks..
