String ExecuteRedirect(int max_redirect = DEFAULT_MAX_REDIRECT,
int retries = DEFAULT_RETRIES, Gate2<int, int> progress = false);

The last parameter, 'progress', defines a callback that is called to show to progress and allow the cancelation.

Progress class has 'operator Gate2<int, int>()', means you can directly connect it here, e.g. this should work:

Progress pi("Loading");
x.ExecuteRedirect(DEFAULT_MAX_REDIRECT, DEFAULT_RETRIES, pi);

Hi, it should be:

x.ExecuteRedirect(HttpClient::DEFAULT_MAX_REDIRECT, HttpClient::DEFAULT_RETRIES, pi);
