Question

I know that http GET can be limited by the browser but what if you are using an iPhone? What is the limit if I do something like this?

 NSString *urlString = [NSString stringWithFormat:@"http://www.hdsjskdjas.com/urlPop.php?vID=%@&pop=%d&tId=%@",videoId,pushPull,[objectSaver openWithKey:@"userId"]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]];
NSURLConnection *connect = [[NSURLConnection alloc] initWithRequest:request delegate:self];

if(connect) {
  //success;
} else {
    //failure;
}

Using this method to send information to my server what would be the limit to the number of characters in the url?

I want to be able to send over 24,000 characters to my sever…

If this is unachievable what would another option be?

To send big chunks of data you should use POST instead of GET.
Here is an example of how to use it:

NSArray *keys = [NSArray arrayWithObjects:@"Content-Type", @"Accept", @"Authorization", nil]; 
NSArray *objects = [NSArray arrayWithObjects:@"application/json", @"application/json", mytoken, nil];
NSDictionary *headerFieldsDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
NSData *bodyData = [body dataUsingEncoding: NSUTF8StringEncoding];

NSMutableURLRequest *theRequest = [[[NSMutableURLRequest alloc] init] autorelease];
[theRequest setURL:[NSURL URLWithString:url]];
[theRequest setHTTPMethod:@"POST"];
[theRequest setTimeoutInterval:timeout];
[theRequest setAllHTTPHeaderFields:headerFieldsDict];
[theRequest setHTTPBody:bodyData]; 

NSLog(@"userSendURL URL: %@ \n",url);

self.conn = [[[NSURLConnection alloc] initWithRequest:theRequest delegate:self] autorelease];

In this case body is a simple NSString object, but it can be anything that you can insert in a NSData object
