Hi

I would like to know that best way of adding data to the session state
object.

I have a page with a series of links such as:
   designs.aspx?categoryID=1
   designs.aspx?categoryID=2

When I get to the designs page I can then add the chosen category to the
session object and perform any other tasks based on the chosen category.

Rather than always passing the data between pages using the URL and letting
the next page update the session state, is there a way of updating the
session state when the page closes.  Therefore the next page does not need
to worry about updating the session state and can just query the session
state object to retrieve any data set from the previous form, for example
the chosen category.
