hope this fix your issue Yes the .NET code will automatically wait for the response and will not execute until response has been received. In .Net 4.5 async has been added by using which you can go ahead before respose is received you need to learn more about code execution of .NET. PLease refer to MSDN or search on google for more details.

seems to work fine The overall structure of your code looks right.
byteRead = stream.Read(buffer, 0, 1000); will block until all of the response data is retrieved from the server. If the remote server shuts down the connection (timeout, etc), 0 will be returned.

it should still fix some issue The reason you are getting undefined is because when you call your callback your are not passing it the doc. That line should look like callback(doc).
Here is an updated version of your code with a few suggestions:
code :
MongoClient.connect('mongodb://localhost:27017/main', function (err, db) {

    if(err) throw err;

    var query = { name : "www.website.com"}

    findOne(db, query, function (err, doc) {
        if(err) {
            // something went wrong
            console.log(err);
            return;
        }

        if(doc) {
            console.log('account exists');
            console.dir(doc);
        } else {
            console.log('good to go');
        }

    });

});

var findOne = function (db, query, callback) {
    db.collection('accounts').findOne(query, function (err, doc) {

        db.close();

        if(err) {
            // don't use throw when in async code
            // the convention is to call your callback with the error
            // as the first argument (notice that I added an argument 
            // to the definition of your callback above)
            callback(err);
        }
        else {
            // call your callback with no error and the data
            callback(null, doc);
        }


    });
}

I wish this help you Following code is describe simple example with POST method.(How can pass data by POST method)
You can use the following code snippet, as described in this article:
code :
NSString *post = [NSString stringWithFormat:@"&Username=%@&Password=%@",@"username",@"password"];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.abcde.com/xyz/login.aspx"]]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"];
[request setHTTPBody:postData];
NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if(conn)
{
NSLog(@”Connection Successful”)
}
else
{
NSLog(@”Connection could not be made”);
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData*)data
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
- (void)connectionDidFinishLoading:(NSURLConnection *)connection

hope this fix your issue Okay, so you're trying to use AWS IoT to create a monitoring system to detect if your device (laptop) is alive or not.
Sending data from the cloud -> laptop is not needed. You can do this by only sending data from your laptop -> cloud.
