When should I use SessionState to store variable values?

Question

Can I say something like

"If you have these situations, then SessionState must be used to store your values ​​between postbacks."

Can you list me the main reasons why the asp.net developer switches the SessionState from ViewState or HiddenFields or querystrings?

thank

Answer 4

:

• If you have a relatively large amount of data that you want to associate with the user. In these cases, the ViewState is very slow if you are dealing with postbacks (something over 150K can really slow down the crawl responses), and the request is completely inappropriate (due to the size of the URL, as well as the strict length restrictions imposed by the web -services and browsers.)
