Including Data in a URL

To understand what's going on, let's look at a URL we could use to view the ShowTimes page.

As you can see, the page name is followed by

?FilmID=1

which passes a name-value pair of “FilmID” and “1” to the server. Note that passing this particular name-value pair to the server will only succeed in retrieving data if there is a row in the Cinema.Show table that has a value of 1 for Film. Use the Caché System Management Portal to inspect your Show table to determine a valid value for Film.
