session management under XSP

[Drasko Kokic <dr...@yahoo.com>]

Hi there,

would anybody have any docs/code samples about session
control?!

also, i am stuck trying to pass one of my variables
into the ESQL block ... is that posible?!  would that
cause Cocoon to get into loop and never finish
processing?!

Thanks for help
Drasko
