Hi,
I have developed a site that allows users to post details for others to view. Within this I have built a secure login process that uses cookies to help the user around the site.
However, when using sites like facebook, I notice that I receive emails with links that pnce clicked automatically take me through the verification process (i.e. check my cookie and if not set allow me to logon) and then take me to a specific page, i.e. http://somedomain/somesubfolder/somefile.php?something=lotsofnumbers
I am assuming this page does not actually exist on the server, and the url and numbers somehow work with the session to identify the user then compile the correct data for the user to view.
I would like to implement a similar methodology but have no idea of where to start or to start reading.
Can someone point me i the right direction please?
Many thanks
