| Never mind that was easy, just added this function to mnet: 
 
 
String mnetHttpPost( String urlStr, String postStr, int timeoutConnection, int timeoutSocket )
{
    NSString *urlString = urlStr.ToNSString();
    NSString *postString = postStr.ToNSString();
    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:urlString]];
    float timeout = (float)timeoutConnection / 1000.0f;
    [request setTimeoutInterval:timeout];
    [request setHTTPMethod: @"POST"];
    
    [request setValue:[NSString stringWithFormat:@"%d", [postString length]]forHTTPHeaderField:@"Content-length"];
    
    [request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
    
    NSData *response = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil];
    NSString *stringResponse = [[NSString alloc] initWithData: response encoding: NSUTF8StringEncoding];
    
    return String( stringResponse );
}
