To the best of my knowledge, there are seven methods to pass parameters
between web forms. Session variable method is the one I used most frequently.
Any comments are warmly welcomed!
1. global variables in Gloable.asax
2. application variables: Application["username"]="peter"; //any type of data
3. session variables: Session["username"]="peter"; //any type of data
4. viewState variables: ViewState["username"]="peter"; //only String data type
can be used
5. Context: Context.Items["username"] = "

Session uses too much resources when the server runs under load.
ViewState does not work well with different pages. As 1,2,3, it does not work
for different pages under different applications.
Server.Transfer has to transfer to the same application either.
Redirect works great, except the URL size has limitation(1K)
Cookies depend on browser support.
Next version of ASP.net will support it :)

frequently.
