Yii2 如果其他注册用户在 URL 上，如何阻止对 URL 的访问？

Question

My today goal is to make URL unavailable to other registered users if one of the user opened that URL and make it available when this user leaves it. Right now I have only idea how to block it - using cache, but problem is with unblocking as user can go everywhere or even just close the browser. I know that there is option for set cache timer, but in my case this is NOT an option - system must know if there is some user in that URL. Can someone help me with some ideas how to achieve this?

Only thing I can personally think of is using JWT or sessions to check if a logged in user is on that page, then a condition to check if the current user is not equal user that is trying to get on the page, and if it doesn't match just redirect that user to somewhere else.

 export const blockAccess = expressAsyncHandler(async (req, res, next) => { //check if the user is currently on the page if (req.session.promoPage) { //if they are, redirect new user's that're trying to access the page to the home page if (req.session.promoPage.userId.== req.user.id) { res.redirect('/') } } next() //next here is a function that tells the program to move on to the next middleware function or route etc.... })
