We use wget to trigger builds from an external trigger. We have a 20 minute quiet time set on this project. When the first wget is called, it triggers the job and starts the quiet period timer. However, subsequent identical calls will not reset the timer. It continues to count down from the first call.
Here are the calls I see in the log:
-bash-4.1$ wget -v --delete-after 'http://SERVERNAME/buildByToken/build?job=BUILD_NAME&token=TOKEN_NAME'
