CEF Forum

Hi, I doing browser app and having problem about how to custom header request. I want add "X-Forwarded-For" to header request when browser start request http. I have used OnBeforeResourceLoad from CefRequestHandler:

CefRequestHandler::ReturnValue ClientHandle::OnBeforeResourceLoad(CefRefPtr<CefBrowser> browser, CefRefPtr<CefFrame> frame, CefRefPtr<CefRequest> request, CefRefPtr< CefRequestCallback > callback)
{

CEF_REQUIRE_IO_THREAD();

CefRequest::HeaderMap hdrMap;
request->GetHeaderMap(hdrMap);

hdrMap.erase("X-Forwarded-For");
hdrMap.insert(std::make_pair("X-Forwarded-For", "16.30.1.150"));
request->SetHeaderMap(hdrMap);
return RV_CONTINUE;
}

But it don't success.
Thanks

What about adding other headers does it work at all?
