Does AJAX(javascript) have user session functionality? I want to use AJAX PHP and MYSQL to dynamically update my static HTML page. I have got an example to work where I push and pull data out of an HTML page using AJAX, but now I want to break it up and allow individual users to do the same thing with their own data. They will have to have their own sessions / sign ins to do this ... what is the best strategy for them to do this?
Do all my .HTML pages need to be .PHP pages now? (at lease where I want to force a sign in)?
