title: How to redirect to a private Google Group?
body: <p>Now, I wish to redirect to a private Google group on click of a button on my website along with search parameters. I have generated the required URL using perl. Then I made a simple redirection using . It works when the user is already logged in(using cookies). But it doesn't work if the user has not logged in. I wish to redirect to Google's login page to make sure the user has logged in and thus can access the private group. How do I do this? I read some documentation mentioning OAuth. Is this the only way? </p>
