on 127.0.0.1, your html code should be:

$.ajax({
    url: "http://127.0.0.1/a/w/currencies",
    type: "GET",
    dataType: "json",
    data: {
    },
    success: function(data){
        console.log(data);
    }
}); 

on 127.0.0.1, your apache conf should be:

...


            ...
            ProxyPass / https://app.somesite.com:5002/
            ProxyPassReverse / https://app.somesitecom:5002/
            ...

on this case, your browser will not cross-domain, because your url and ajax use the same domain.But exactly, ajax request https://app.somesite.com:5002/ , I don't know if it is a reverse-proxy ,but it seems work for me. Have a try :)
