I just wanted to add one more caviat (sp?) to what Ryan said.
For static variables, the runtime guarantees that only one instance is
created PER APP DOMAIN.
IIRC, If you have recycling configured in IIS6, that is done by
creating new App Domains. So, the object /could/ be recreated at any
time. And any info you "stored" in that object could be lost (unless
you do something special to prevent it).
I don't have any idea how recycling would interact with the <object> tag.
