I have set up a custom protocol for Internet Explorer by following this thread (Open Internet Explorer from Chrome using a protocol handler (ie:url)), and I can launch the IE window by window.open('ie:https://****') to show the new page. However, this page requires a cookie that is stored in Chrome, is there any way to pass the cookie to IE during the way, without relying on any extension?
As per my search results, it is not possible to pass cookies from Chrome to IE through the custom protocol handler.
Browsers do not have this feature to share the cookie with other browsers.
Cookies meant to be used for that specific browser on which it is created.
Below are the helpful threads.
