ASP Variables
A variable is employed to store information.
If the variable is stated outside a procedure
it can be changed by any script in the ASP file.
If the variable is declared within a procedure,
it is shaped and destroyed every time the procedure
is carried out.
Lifetime of Variables
A variable declared outside a procedure can be
accessed and changed by any script in the ASP
file.
A variable declared inside a procedure is created
and destroyed every time the procedure is executed.
No scripts outside the procedure can access or
change the variable.
To declare variables accessible to more than one
ASP file, declare them as session variables or
application variables.
Session Variables
Session variables are used to store information
about ONE single user, and are available to all
pages in one application. Typically information
stored in session variables are name, id, and
preferences.
Application Variables
Application variables are also accessible to all
pages in one application. Application variables
are used to store information about ALL users
in a precise application.
