how to send a GET request - but only send not to get the response?
U used HttpURLConnection and URLConnection and this type of operation only work if I get the inputStream (in that time the request is sent).
If now the connection is broken thread waits 300ms to continue - but I don't need to wait, I'm not interested in the response, I just want to send it.
HttpURLConnection connection = (HttpURLConnection)left.openConnection();
The is a second disadvantage of this: If the connection is back and I've for example 3 times called the function above it will be executed 3 time - how to clear the cache of the connection to prevent it?
