It'd be really great to be able to extract the Authorization header out to the Header Manager, so that can can keep the script valid by simply updating the Bearer token.

With the parameter remove_cookie the program will remove all cookies may be also the Authorization, set to false to keep all cookie values.

With the parameter remove_cache_request the program will remove cache informations.

if (harRequest.getHeaders() != null && harRequest.getHeaders().size() > 0) {
for (HarHeader header : harRequest.getHeaders()) {
String headerName = header.getName();
String headerValue = header.getValue();

            if ("Cookie".equalsIgnoreCase(headerName)) {
                if (isRemoveCookie) {
                    // no cookie because add a Cookie Manager
                    addThisHearder = false;
                }
            }

                if (isRemoveCacheRequest) {
                    // no cache If-Modified-Since or If-None-Match because add a Cache Manager
