I logged into an online forum created by using PHP and was browsing some topics in the web site.
Since the weather was hot, I got to have a bath and left my computer idle for a short while.
When I came back to my computer, I pressed a “Add Post” icon.
But When I pressed to submit the new topic,the web site redirected me to the Log in page,
I gussed my cookie might have been expired. And then after I logged into the web site again,
my new post was created. I am wondering how they do this.
What is the method and technique they used?
Did they store my new post to a new cookie or session first when they found that my cookie was expired?
You could do that by storing the post’s content into a cookie and once you log the user in, check the cookies that you have set. If you have a cookie set with the content you would create a post with, create the post and remove the cookie. This should work with sessions as well. All depends on how you set your login system.
