Take a look at NSURLConnection. You essentially create a connection, register a delegate, kick off the request and build the response as the data is passed to your delegate.

I'm working from memory here, but essentially:

• Create an NSURLRequest for your request to your server
• Create an NSURLConnection using the initWithRequest:(NSURLRequest *)request delegate:(id)delegate init method, passing a suitable delegate.

The request will be made, and the response will be passed back to your delegate in:

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data

I've not tested this, but something like:

NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"SERVER"] 

[request setHTTPMethod:@"POST"]; 
[request setHTTPBody:@"Your XML"];

NSURLConnection * conn = [[NSURLConnection alloc] initWithRequest:request delegate:self]; 

Then in your delegate you can build the response using the data provided in the didReceiveData:(NSData *)data and didReceiveResponse:(NSURLResponse *)response methods.
