title: Cannot send string request to server in IOS(weird)
body: <pre><code>NSURL *URL=[NSURL URLWithString:@"http://xxx.aspx"];
  NSString *request=@"__EVENTTARGET=17&amp;__EVENTARGUMENT=25";
  NSMutableURLRequest *urlRequest=[NSMutableURLRequest requestWithURL:URL];    
  [urlRequest setHTTPMethod:@"POST"];
  [urlRequest setHTTPBody:[request dataUsingEncoding:NSUTF8StringEncoding]];
  NSString *returnString = [[NSString alloc] initWithData:
                      [NSURLConnection sendSynchronousRequest:urlRequest 
                                            returningResponse:nil error:nil]  
                 encoding:NSUTF8StringEncoding];
  NSLog(@"%@",returnString);
  </code></pre>
  
  <p>When I'm trying to send just <code>NSString *request=@"__EVENTTARGET=%@&amp;__EVENTARGUMENT=25"</code>; Everything is working! It logs generated html code.</p>
  
  <p>BUT! when I'm trying this one(Everything the same except I have to send token from EditText):</p>
  
  <pre><code>NSString *token=@"23";   //23 from edit for example
  NSURL *URL=[NSURL URLWithString:@"http://xxx.aspx"];
  NSString *request=[NSString stringWithFormat:@"__EVENTTARGET=%@&amp;__EVENTARGUMENT=25",token];
  NSMutableURLRequest *urlRequest=[NSMutableURLRequest requestWithURL:URL];    
  [urlRequest setHTTPMethod:@"POST"];
  [urlRequest setHTTPBody:[request dataUsingEncoding:NSUTF8StringEncoding]];
  NSString *returnString = [[NSString alloc] initWithData:
          [NSURLConnection sendSynchronousRequest:urlRequest 
                                returningResponse:nil error:nil] 
          encoding:NSUTF8StringEncoding];
  NSLog(@"%@",returnString);
  </code></pre>
  
  <p>It logs just xxx.aspx html code as I never sent anything</p>
  
  <p>Weird! Does anyone know what the problem?? Thanks!</p>
