Not at all - provided you don't stuff the whole video in there instead of a file name or similar they are very, very useful. But the persistence of cookies can have advantages, particularly if the user might want to use it tomorrow (or finish what he is doing later). Since session data is only persistent while the browser session is still open, and for a limit time (MS recommend no more than 20 minutes and that's not unreasonable) it makes a lot of sense to use cookies. I just don't store security info outside the server! I didn't know there was a "sessions are bad" faction - it's probably the same bunch as the "break in a loop is bad" faction.

They are just afraid of Ivan Drago. Though, FYI, it's usually called a "ring", not a "loop".

If you have to move to web page 2 on a button click on page one, and page 2 totally depends on data input by user on page one, what approach would you choose to share data between the pages? Would it be session or cross-post or something else? Any why?

That depends. Do you need to run any logic from page 1 before you move to page 2? If not, just use
<form action="page2.ext">- you'll save the user a round-trip to the server.

They can leave my ring well alone! :laugh:

I always use Sessions (unless I'm trying to pass a huge object and then I'll just pass a reference to it instead).

Session or cookies, depending on how non-volatile I wanted the data. I generally try to make data last as long as the user is probably going to need it - except security info, which never leaves the server so is session limited at best.

Keep in mind as well, for storing things in the session, you should not store objects that are not agile. (Agile objects being defined as... objects which do not maintain a reference to system resources, DB connections, open file handles, etc.). Session is also server dependant, if you use session to store objects, your server balancing must be a sticky balancing paradigm where once you hit a particular server, you remain with that server for the duration of the session.

Thanks: I thought that was lost on everyone.

+1 And, of course, make sure that objects are serializable (like proper DTOs), so "the next guy" (which is yours truly) doesn't want to come after you wielding an axe because stuffing ListItemCollections and GridViewRows into Session makes the StateServer unhappy . :mad:

My previous employer banned session variables. They projected millions of users and didn't want all that memory floating around for 20 minutes before being released in the case the user was just there for a second. Their other argument was that they were going to a server farm and didn't want to keep the sessions coordinated. The place I'm at now does not have that much traffic so Sessions are fine with us. Our problem is sessions timing out and the users complaining they lost their work will they were yakking on the phone. We use cookies as well, but not as much. Some of our users are still terrified of cookies and disable them. In worst cases we stash the data in a database record and pull it back later. Not a good solution either.

Actually, I normally prefer to use ViewState and stay on the same page, swapping elements on the button press. If I really have to pass data to a different page, I would normally use session variables. I don't like to use cookies for anything other than authentication, although they can be good for shopping carts and other things that you want to persist beyond the session.

Agreed - there is the fun of redundant DB entries then...and no built in mechanism to expire old data.

I prefer session variables to share info between pages.

I believe it depend of the size and sensitivity of the data you just passing. There are whole religions in favor every method. In my opinion a good programmer will never set a barrier just for the shake of 'preferences', but will learn the needs and deeds of the system an act in the best way...
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is (V).
