Currently, Java Update downloads multiple XML files and exe during the update process. However, because user machines may connect to java.sun.com through proxy server, the cache in the proxy server may be used to increase the connection performance for the user machines. This is good in general, except java.sun.com no longer receive every single HTTP request for downloading the file, thus it makes very difficult for us to determine what the actual total number of downloads of the JRE through Java Update.

One way to solve this issue is to modify Java Update to send a HTTP HEAD request to a predefined JRE version specific URL at java.sun.com after the update is successfully installed, so we could track the success rate of the update download simply filtering the HEAD requests for these URLs in the server log.
