Question

How do I prevent caching of HTTP requests?

Answer

By default, caching will be enabled. You must use a URLConnection, rather than the URL.openStream() method, and explicitly specify that you do not want to cache the requests. This is achieved by calling the URLConnection.setUseCaches(boolean) method with a value of false.

// Create a URLConnection object
URLConnection connection = myURL.openConnection();

// Disable caching
connection.setUseCaches(false);

// Connect to remote machine
connection.connect();
