问题 I am using HttpWebRequest for REST services which uses some basic authentication that relies on JSESSIONID cookie. I need to pass that cookie to WebBrowser control to reuse that session, but didn't find any usable solution that would allow me to pass that cookie in the Browser's cookie store. Is there any way?
