Simple HTTP request

Question

Hello all,
Hope u all will be fine and fit. I want to make an http get request to my server and the response to that request would be an xml file. Do anyone knows how to do this in a simpler way. I just need a sample code to send and receive a http request and response.
Currently i m doing in this way
NSData *nsDataObject = [[NSData alloc] initWithContentsOfURL:URLObjectForMyServer]];
Also please tell me if this is the correct way of doing it?
Quick replies will be highly appreciated.
Regards,
Obaid

Hi Obaid,
I thnk you should fire request like that and u want xml file as response so that u have to write code in your server side that will covert data into xml format and return as a string....
NSString *post = [[NSString alloc] initWithFormat:your query string];
//NSLog(post);
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:@"url of ur server"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:request delegate:self];
if (conn){
NSLog(@"Data Recieved");
receivedData = [[NSMutableData data] retain];
else{
any error is occured
hope that it will help to u
