Check for Updates, new with Application Express 4.0, allows for you to easily discover, download, and install new Application Express functionality and up-to-date patches.
When you use the Check for Updates feature, Application Express issues an HTTP request to the Oracle server where the update center is located, in a very similar way to browsing a URL from your web browser. The automatic Check for Updates feature is enabled by default, so Application Express will issue an HTTP request on initial startup. The following describes what information is sent to the server as part of that request, and how you can opt out of sending the requests if you are uncomfortable with it.
What Information is Sent
In order to provide the best possible service to our users, Application Express sends a few pieces of data as part of any Check for Updates command in addition to what is automatically sent by the browser in a HTTP request. The following is a list of the information dispatched over the network from Application Express:
Application Express version
APEX Listener version, if the APEX Listener is being used
Additional, non-identifying information is also sent by the browser in accordance with the HTTP specification.
