http header file size = 0

[Shades of Chaos]

Hey all,

I am trying to get the user agent but when I try and read it, it comes out (null)

NSLog(@"user agent = %@", [request valueForHTTPHeaderField: @"User-Agent"]);

request is an NSURLRequest. So I tried to get the http headers and I don't think there are any. When I use

NSLog(@"http headers = %d", [[req allHTTPHeaderFields] fileSize]);

it prints out zero. req is an NSMutableURLRequest. Does anyone know why this is happening.

Thanks
Clinton
