How to configure laravel 5 and gclid

How should I confugure laravel 5 with gclid ?

There is an article https: //support.google.com/analytics/answer/293824 ... When I try to pass a test parameter https://mysite.com.ua/?gclid=TeSter-123, gclid becomes lowercase https://mysite.com.ua/?gclid=tester-123

Perhaps there should be done something in htaccess ? Or maybe there are other ways?
