Handling double slash // in URL path by Load Balancer

We have a website running on Beanstalk and served behind an application load balancer. When there is double slash in the URL e.g. https://example.com/en//page/path/ the load balancer forwards the request to https://example.com/en/page/path/ even though the URL in the browser remains as https://example.com/en//page/path/. How can we handle this so that the load balancer either forwards the request with the double slash to beanstalk or does a 301 redirect to sigle slash url.
