1. In a shared hosting environment if you do proper locking
of session variables in your application and another application
does not how does that affect you?
Negatively. That is, you can be as vigilant as possible with locking, but if
another application isn't, that application may cause server instability,
and if sharing the same scope such as the Server scope, will ignore the
locks you've placed on the scope when your app uses it.
2. If the answer to number 1 is that it destabalizes your
application would it then be better to have variables stored
in cookies rather than session variables?
Perhaps, in the sense that you'd be less likely to have concurrency
problems, all other things being equal. However, if the other app causes the
server to crash all by itself, your app won't run very well.
