Pass more information to RequestModifier

[WalterWoshid]

The RequestModifier looks like this:

export function modifyRequest(httpRequest, requestModifier) {
    const request = {
        url: httpRequest.url,
        method: httpRequest.method,
        headers: Object.assign({}, httpRequest.headers),
        credentials: httpRequest.withCredentials ? 'include' : undefined,
    };

    return Promise.resolve(requestModifier.modifyRequest(request))
        .then(() =>
            Object.assign(httpRequest, request, { withCredentials: request.credentials === 'include' })
        );
}

I am trying to fetch a video source, but because of CORS errors that are not fixable, I created a proxy controller on my backend, which fetches a request (that usually results in a CORS error) and returns the result (now without the CORS error).

But trying to overload the modifyRequest is not the most optimal solution, I see that a Range header is set, but I can't access it in the extended method. Without it, my proxy controller tries to download the whole file which is sub-optimal.

A simple fix like this would be good enough for me:

    const request = {
        range: httpRequest.request.range,
        url: httpRequest.url,
