iPhone User-Agent

Question

I'm getching content in a universal iOS app using:

NSString stringWithContentsOfURL: [ NSURL URLWithString: link ]

... does that send iPhone/iPad user's IP and User-Agent to the server from which its fetching content from?

I need it to send at least user-agent so I can detect whether its an iPhone or iPad and optimize the content accordingly.

You can use the code below to make sure that the devices is sending an user agent by manually specifying which one to use.

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
{
    NSString* userAgent = @"Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10";
    NSURL* url = [NSURL URLWithString:@"http://www.myWebSite.com/"];
    NSMutableURLRequest* request = [[[NSMutableURLRequest alloc] initWithURL:url]
                                    autorelease];
    [request setValue:userAgent forHTTPHeaderField:@"User-Agent"];

    NSURLResponse* response = nil;
    NSError* error = nil;
    NSData* data = [NSURLConnection sendSynchronousRequest:request
                                         returningResponse:&response
                                                     error:&error];
}

NOTE: The sample user agent I've listed may be dated, and you MAY need to find a newer one.
