How to determine if a Session Variable exists?

[Shapper]

Hello,

How to determine if a Session Variable exists?

In Page_Load I need to check is Session("MyVar") Exists.
If it doesn't exist then I created it and give it a value:
Session("myVar") = "Value"

Thanks,
Miguel

If variable doesn't exist then its null. Simlpy.

Simply do this..

if ( Session("MyVar") == "" )
{
Session("MyVar") = "Your Value"
}

Ancient Zen problem:

If a Session variable is set, and there is no class to read it, does it
consume resources?
