My pages are as follows(I write only pages which matter this problem).
index.php(1st SPA main page and not restricted)
-signin.php (/signin) (1st SPA content page)
-voting_list.php(/voting/list) (1st SPA content page)
page.php(2nd SPA main page and restricted)
-sethbrogan.php (/voting/vote/sethbrogan) (2nd SPA content page)
I want to redirect, those who visit /voting/vote/sethbrogan by clicking the button on /voting/list, to /singin .
To answer this question, might be yes. Is this possible?
