void setsession( |

Assigns the string value to the session variable named by sessionvar. Session variables are persistent between page accesses and can later be read by session().
Example 50. setsession Example
// Get the next counter value. The counter starts at zero and is increased
// each time the page is accessed. Note that the first time the page is
// accesses the session variable "next-counter-value" won't exist so
// session("next-counter-value") will return "", but (int)"" is defined to be
// zero so it all works as expected.
int counter = (int)session("next-counter-value");
setsession("next-counter-value", (string)(counter + 1));
