I'm developing a Windows desktop application in C++ and I'm using CEF as the browser engine for this application (based on the cefclient example).
Recently I updated the CEF version to "95.7.12+g99c4ac0+chromium-95.0.4638.54" and I'm noticing something strange in the logs.
At least it's strange to me because I didn't notice it before the update (maybe I just missed it). Usually the log file is called "debug.log".
Aproximately one minute after starting the application there is a network request to "https://update.googleapis.com/". In the log file I see the following lines (I've abbreviated the values of the GET parameters "cup2key" and "cup2hreq").
According to the timestamps in the log file, the application was started at 11.30 am. After one minute (11.31 am) the following lines appear in the log (among a bunch of other stuff of course):
- Code: Select all
[1105/113100.612:VERBOSE1:network_delegate.cc(34)] NetworkDelegate::NotifyBeforeURLRequest: https://update.googleapis.com/service/update2/json?cup2key=xxx&cup2hreq=abc123
[1105/113100.768:VERBOSE1:request_sender.cc(181)] Request completed from url: https://update.googleapis.com/service/update2/json?cup2key=xxx&cup2hreq=abc123
[1105/113100.768:VERBOSE1:component_updater_service.cc(389)] Update completed with error 0
I have a few questions:
Why is CEF pinging and or downloading something from this url?
What components are beeing updated and why is this necessary?
Can this behavior be configured or event disabled completely?
Thanks for your help
