java - DWR 是否使用基于轮询或推送的概念？

Question

虽然 DWR 被称为反向 AJAX 技术，但我想了解它是否实际上使用基于推送的概念，或者实际上是基于轮询的..

如果您可以通过简单的示例详细说明相同的内容以更好地理解该概念，那就太好了。

Answer 1

DWR can use both depending on the browser used.

If the browser supports push DWR can use this.

If the browser does not support push then DWR will use a polling mechanism.

You can read all this in the documentation.
