Regarding proxy server authentication RRS feed

  • Question

  • This question is not at all about proxy configuration. It is about proxy authentication. In my college, we use the campus LAN network, where the first thing which opens after opening the browser (which should actually open) is ironport authentication from the proxy server where I have to enter my user id and password.

    The problem is that Internet explorer tries to connect to the proxy server after some redirections but doesn't prompt for authentication, leading to error. I have to start firefox for the same as it gives no problem, still want to use IE 11.

    The page which should open is some https connection to ironport but rather asks to fix connection errors.

    Any help will be appreciated.
