How to read incoming http request headers of a wix page?

I am able to get the request query parameters, but I also wanted to get the custom http headers that comes along with the incoming request to my page.

example: my page url is https: // mywixdomain . com/mypage?param1=s&param2=g
but I also wanted to get the headers that comes along with the request on mypage.

Thanks a lot for your help
