Hi Madison,

Regarding on the State management questions you mentioned, here are some of
my understanding and suggestion:

ViewState is a media for persist some data across the postback of a certain
page, however, since it is stored in a hidden html input field in page's
html content, you should avoid store large number of data into it.
Otherwise, your page's size(response & request size) will be huge which
will surely slow down the response experience. here are some good articles
help you better understand ASP.NET viewstate:

Session, Cache are both common storage in ASP.NET for store some data at
server-side. Session is good at store per-user data, however, you should
also avoid storing too much data into it, as you need to manually take care
of clearing the data in sessionstate(unless session timeout).

Cache though is not per-user specfiic, has a great advantage, it support
invalidate/timeout policy. You can use CacheDependency to control how a
cached object will expire(invalidate), include:

** File based dependency
** normal time period based timeout dependency
** Sql DataBase dependency(new in 2.0)
** or implement your own cache dependency
