Authentication and sessions - the right way?

Hi, I have a problem with designing authentication and session properly. I asked for help some time ago, but I was not able to fix the problem. I have a standard situation - I have an app that has bunch of pages and only main page with login form should be accessible for everyone. Everything else

Re: Authentication and sessions - the right way?

But would it be possible to store User data in the session without having to fetch it from datastore on every request? My users don't interact with each other and they operate only on their own data. So it'd be most efficient to store User data in the session and interact with db only when some dat

Re: Authentication and sessions - the right way?

So it's normal that I lose User data when I move from login to main page and I will have to fetch it from db quite often. When will it happen? I have users browsing around my app, doing most often nothing. Plenty of labels with gets. Will browsing like that trigger fetching user data from db? Or w

Re: Authentication and sessions - the right way?

Marco: And it works without problems? There is no issue with user trying to log from 2 browser on same time, trying to cheat the system? I am just wondering if there is any risk of that. How does your code look then in session and how do you fetch your data? Martin: I was trying to save on cos

Re: Authentication and sessions - the right way?

I'd say it's mostly a cache. >From estimates I can say that 80-90% of the time data will be read-only. Only remaining 10-20% will be data manipulation. My current implementation is that I use setters on data in Session and then persist whole User. Like that: MySession.get().getUser().setFree_la

PropertyModel not refreshing

Hi, I have a form with labels that use PropertyModel. They work fine when I test them locally - when I click on submit button I get proper refreshed values in labels. But when I deploy my app it does not work, I still get old values. Where can be the problem? I am using Wicket 1.4.17 and deploying

checkGroup - 2 out of 5?

DataView the easy way?

Re: Links blocked when I enter page

Well, they don't do it in my case. Maybe because they are in panel... Anyway, I wouldn't have problem with that. It's that 2 other links are blocked, those that lead to other pages. I don't have problem like that on other pages and only thing here that is different is that additional submit button
